OK, I have an OC Catleap on order, my problem is that with my 2C Catleap,
I only get 60FPS (BF3) with my Gigabyte GTX580 3GB card (I use V-SYNC in games as I find it much smoother).
I am tossing up whether to get another Gigabyte GTX580 3gb (found one on eBay) or sell the one I have and
buy a GTX680/HD7970.
I really want to take advantage of the OC Catleaps potential but am afraid with a single GTX580, it won't
be enough.
I know GTX580's SLI will out perform a single GTX680 BUT it will limit me to 102Hz and I don't think a single
GTX680 could reach 120FPS with the Catleap (likewise with a HD7970)
I will also need to purchase a Waterblock for whatever I decide. If I go the SLI route, it is going to be
really tight in my case (look in the build logs section, lower radiator and second GPU would be tight fit).
It will fit but would need to re-asses the tubes from GPU2 to radiator.
Funds are an issue too so need to be wary of that.
Should I just stick with my single GTX580 wait for the next line of GPU's to be released?

Any thoughts would be appreciated.

Cheers ;)

If funds are an issue, I would go with a GTX670 instead. Within 5% performance of 680, but much cheaper.

In fact, I I just upgraded my GTX580 to a Gigabyte GTX670 in preparation for the new screen. A nice boost of around 35% in benchmarks after overclocking it. Also amazingly silent (despite 3 fans). Highly recommended.

Then again, 1440p adds around 78% more pixels over 1080p. Might have to get another 670. :)

Yeah I thought about the GTX670 but I figured one wouldn't be enough, would need 2 to get the most out of the OC Catleap I think.
If a dual card set up is what is needed, then the SLI GTX580 option is probably the cheapest but ... have to consider the extra hassle plus
the fact GTX 580's are old tech now ..... hard to make a decision that's why I'm after opinions.
Pretty much decided that if I do upgrade 'now' to a single GPU it would either be a GTX680 or HD7970 as I would cover some of
the cost from the sale of my GTX580.

What would make the most sense would be 580 sli now and then get the 700 series when they hit...

Why would you want 580 SLI when it is old, more expensive and less power than 670 SLI? And waiting for the next generation is a neverending wait. I have a 670 and most demanding games (BF3, Witcher 2, Metro 2033) need to be set to low/medium to average around 80-100 FPS. Im tempted to get another one :)

sli 580 can barely keep up with a single 680 in some games. Definitely don't recommend it. Go for a 670. That way if you wanted to up your performance, you could just drop another card on it.

I was considering to get a 670, but that would be a downgrade in performance as I have sli 570s. I'm going to wait for the next generation of GPUs.

Does anyone have a single GTX 680 and an OC Catleap? What FPS are you getting?
I would prefer to go for a Single card set up if possible, and I know with GTX 670 I would need to SLI to get close to 100-120FPS
and that means outlaying cash for two cards something (for the meantime at least) I would rather avoid.
Now price wise I would have thought (if I had to outlay cash for two cards) then Crossfire HD7970's would have been the way to go?
I do like nVidia though ..... too many bloody choices lol

I wouldn't worry so much about SLI limiting you to 103Hz. I have a 680, but as I run Linux-only, the Linux drivers cap the pixel-clock at 400MHz, so I max out at 103Hz. Which is a world of difference from 60Hz. 100+Hz is in the top range of what you can expect from modern high-end-graphics games anyway - I doubt you'll be able to reach 120Hz framerate consistently, whatever setup you get.

I only play 15-year-old tech QuakeLive, so I have a constant framerate of 125Hz, and 103Hz refreshrate is just gorgeous :)

OK I think I am sold on the EVGA GTX670 4gb Superclocked+ Signature:
http://www.evga.com/products/moreInfo.asp?pn=04G-P4-2673-KR&family=GeForce%20600%20Series%20Family&sw=

It has a really short PCB which would be great for my case if I want to run two in SLI and XSPC have an awesome Waterblock for them
473
Backplate:
474

Pretty much made up my mind, one for now and add another later when funds allow ;)

Thanks for the help guys ;)

Crossfire

a) You can't "crossfire" 670's. It's called SLI
b) SLI would limit you to 100Hz. Depending on the game, this may or may not matter.

@ Sneaky: Nice card though, very sexy WC block. I'm not sure I'm convinced you will need 4GB VRAM at this resolution before you are gonna need more overall GPU power, but I will admit going SLI certainly helps there.

Yeah you're right, probably wouldn't need the 4gb VRAM with one OC Catleap but the price of the 4gb card isn't a hell of a lot more than the 2gb variations.

I forgot over at the evga forums they do say that the EVGA GTX 670 is the best card for the money

Yeah unfortunately, I'm in Australia and newegg doesn't ship internationally.
I could use my mail forwarder which I haven't used in a long time ...

2 670 sli? almost 800. If I were you, I would go gtx 690 with 200 more

Bear in mind the short PCB versions of the GTX670 don't overclock as well as the full length ones - the power circuitry isn't as robust. Not a huge difference obviously, but it is there.

The history of flagship cards with 2 memory sizes is that you run out of horsepower long before memory size is a limiting factor. Here even more so since we're having to hit higher framerate targets (60 vs 100+Hz) and thus can't use the levels of MSAA that would exceed 2GB. But as you've said, price difference is relatively small.

Dude ... I don't have $1000 dollars to slap down on Graphics cards in one hit, that's why I said I would get one now and add another at
a later date when funds allow. If money wasn't an issue, heck I'd get 2 GTX690's lol

Why would you pay 200 more for very minor performance boost? Well other than slightly less power consumption and less space required in case, but those shouldnt be a problem if even thinking about 800-1000 for GFX cards.
