Hey everyone! I currently have an EVGA GTX 670 Sig2 2 GB in my main rig (Number Cruncher). I'm also planning a waterloop for my system. Currently, plans are only for a CPU loop, and adding a GPU later. That's just because I'm not sure how long I'll have my GTX 670 for.

Anyway, what do you think would be the best route to take for the next year or year and a half for my GPU in my system? The GPU(s) would be watercooled as well, and my motherboard can only support up to 2 GPU's at most, so tri or quad crossfire/SLI isn't an option for me. I also have a 750W PSU, but I think most current/last gen (7xxx,6xx,7xx cards) would work fine with a 750W PSU in crossfire/SLI.

So, what do you think? I play in 1440p on a single monitor, and really enjoy having awesome looking graphics AKA cranking up the settings. wink.gif All advice will be appreciated! The thing I'm mainly worried about is that in a year or two, 2 GB of VRAM won't be enough for most modern games, so quite possible Battlefield 5, GTA 5 or possibly even 6, etc. I currently play some BF3, a lot of GTA 4, some Sim City, but my most demanding game would probably be BF3.

I would buy a 2nd 670 FTW Sig2 (wait about a month & that price should drop) for a SLI setup...That will be real nice for 1440p. You basically have a disguised 680...Check out the review and see what your FTW Sig2 can do with 1600p... http://www.techpowerup.com/reviews/EVGA/GTX_670_FTW_Signature_2/ thumb.gif

thinking.gif ... That's what I would do but it's your cash whistle.gif

I really love my current card, and I know that with the 7xx series releasing as we speak, the 6xx series prices are dropping. I really do love my card though, it's a great overclocker (1293MHz on the core stable). And I guess if I turn down the AA and special effects in games the 2 GB of VRAM will last me a long time. Thanks for the advice! +Rep!

And the main reason I bought the Sig2 was for the disguised 680 and the good cooler on it as well. devil.gif

Think about it for the moment...The value for the FTW Sig2 670 has dropped since the 770's are for sale.. If you sell it, you'll probably only get about $300 for it (if you're lucky). And if you did decide to sell it, I would not recommend buying a Titan since the 780 can be OCed to be faster than a stock Titan for $350 less...but again, that's my 2cents.gif ...I don't expect a mass of people to agree with me wink.gif

Yeah, the Titans do seem overpriced, and seem like a longshot for me and my budget, and seem *ahem*overkill*ahem*.

If I buy another Sig2 FTW 670, I'll definitely wait until they're on sale. I picked mine up last Christmas for $380, which was an alright price then I though, $70 off the normal price.

Stick to a single GTX 670 now. wait for the next gen AMD cards to launch in Q3 or October. sell the GTX 670 and get the best perf you can for your budget. AMD CF frame pacing driver should be out in July. you will get a good idea if its worth considering AMD for multi GPU.

http://www.overclock.net/t/1395229/chiphel-new-specs-of-radeon-hd8000-leaked

The next gen consoles have massive 8GB unified RAM . PS4 - 7GB for games, Xbox One - 5GB for games. rest is OS and system software. even at 1080p , 2GB is a shortsighted investment.

http://www.anandtech.com/show/6994/nvidia-geforce-gtx-770-review/3

"The wildcard in all of this will be the next-generation consoles, each of which packs 8GB of RAM, which is quite a lot of RAM for video operations even after everything else is accounted for. With most PC games being ports of console games, there’s a decent risk of 2GB cards being undersized when used with high resolutions and the highest quality art assets. The worst case scenario is only that these highest quality assets may not be usable at playable performance, but considering the high performance of every other aspect of GTX 770 that would be a distinct and unfortunate bottleneck

As it stands 2GB feels shortsighted, and for a $400 card, a bit small. Given the low cost of additional RAM, a 4GB baseline likely would have been bearable."

so in conclusion for 1440p get a 3GB or 4GB card.

Good point thumb.gif I will have to agree with this regarding to console gaming. You can definitely count on Sony & Microsoft to utilize the gpu power before releasing the next console. This is the normal procedure when it comes to making games for the console, so when that time comes which will probably be sooner than later, I can see 3Gb being the minimum for gpu's in the future for pc (maybe even 4Gb depending on the development of games).

At this current time, you should have at least a 3Gb gpu at minimum but the OP will at least be fine for the moment with (2) 670 2Gb gpu's.

I have GTX 670 SLI 2GB and its awesome! I'd highly recommend you either buy a second GTX 670 for SLI now or you get a single GTX 780 3GB and get another down the line. I get around 90% scaling with SLI and have had zero issues.

Always hearing of microstuttering issues in crossfire and other issues, i stay away from AMD these days.

Sell your 670 and get two 7970's when the new Crossfire drivers come out in June/July. thumb.gif

Thanks for all the advice everyone! Does anyone else have any thoughts about this? I'm currently leaning towards dual 670's just because or it's performance and price.
