A 460GTX will do, it's very cheap and powerful.
i agree.
sure the 6870 or the 560TI will max the game, but do u really need such a powerful card?!
i think these cards are more powerful than they are useful. they can max every game, sure, but the slightly cheaper cards can do the same on resolutions of 1680X1050.
If you plan on playing on 1900X1200 with AAX8 or whatever than you should go with the strongest and most expensive, but i havent seen a game that came out in the past 5 years that the 460 couldnt nearly max out in 1680X1050.
OP, If you a big gamer than go the extra mile. If you want to max Skyrim than do aim that high. you don't need to. take nvidia's 460.
