Usually I play older games but as of late I've gotten back into Planetside and other more intensive games. However, a Galaxy 650 just won't cut it for the next few years.
I've seen comparisons of regular 460 (non-V2) and the 650. While the V2 is less powerful, is it worth having two of them? Will it equate a 650 Ti Boost, or even a 660? I use just one monitor and the 400 series is getting pretty dated, so it might not be worth it.
Various friends of mine really don't like SLI and tell me it's a way to burn my house down (It's an inside joke because I've actually had a housefire from a computer). Especially for single monitor setups, too, they tell me that SLI is stupid.
