So, I have just about enough for a 4890, which I was all ready to go for, but then I thought, given the res I normally play at (1440*900) and my current specs: E6400@3.2ghz, 2gigs ram, will I see any appreciable difference over something cheaper? Or should I just save the money? Looking to be at around 60 on most games on high settings with that res. Part of me wants to just get the 4890 to be a bit more future proof. Thoughts anyone?
