I've been thinking of upgrading my computer so I can play games with 3 monitors at 1080p each. I already have a 660 Ti and use it with one monitor at 1080p with no issues, and I'd like to know what I should look for to make sure I can reliably play games at high quality with the increased resolution.
Judging by previous threads, my plan should be enough, but I'm wondering if I'd get a better value getting a slightly weaker card or if need more power.
Intel Core i5 3670K 3.40 GHz (Quad Core)
8GB DDR3 ram
600W power supply
How much VRAM does each card have? If only 2GB, then it would work, but that might be pushing it. Many games now surpass the 2GB limit, and I can imagine that future games will as well. However, if you don't want to run everything completely maxed out, anti-aliasing, etc., then you should be fine.
You'd be much better off with 2 GTX 760's http://amzn.to/1ayerlI if you can stretch your budget a bit more. They are the best bang for your buck right now.
The only problem is that OP already has one 660Ti... to buy two 760s would mean either a waste of $300 on the previous 660Ti, or the trouble of having to do something like sell it on Ebay and getting only $180 or so for it... What I would do is wait until the 760Ti is released, sell your 660Ti for as much money as you can muster, and then buy two 760Tis.
