So I have room in my budget (sort of) to upgrade my video card. It is by far the old piece of hardware in my rig. Currently I am using an Nvidia GTS 450
I have around 250 bucks for a budget so I started looking at the benchmarks and I was kind of leaning toward Nvidia GTX 660 Ti
for $235. But then after scanning their Price Performance list I see that the Nvidia GTX 560 Ti
is actually the highest ranked in essentially bang for buck, and I can stretch the budget a little and buy two of them at 140 each ($280).
Now I have read before that running SLI/Crossfire doesn't actually net you the full benefit of a second card, I think I heard somewhere that it was 30% increase or something. I don't know a ton about hardware, pretty much just enough to be able to set up a new rig and get it to run (most of the time, FSB tends to mess me up). However I know some of you actually work in this area and I would like some advice.
Firstly is it worth going with SLI in this case, or would I be better off with a single card? I would save a little money with the single card, not to mention power load and cooling, but I might net a significant increase in performance with two cards. I don't tend to play super graphically intense games, I spend a lot of my time Comfy Trucking and playing MMOs and indie games.
Secondly I am a slightly Nvidia fanboi, but that is only because I have never bothered with Radeon. If I get a Radeon at similar price/performance is there any major simplified pros/cons when compared to Nvidia. I understand both have their nuances and target audience so I don't really need a complex breakdown of when/how/where one is better than the other, a general list would be sufficient.
