Hey, my mate has a fairly old graphics card and he's saving to get another one, probably a 750ti, but for the time being, what can he do to improve his performance in games, such as Bf3.
He can try overclocking it a bit if he hasn't yet, its not too hard.
Btw. when he goes to get a new one tell him no matter what do not buy a 750Ti. Its built to use little power and because of that Nvidia charges a huge chunk of cash for it. It wasn't designed for high performance though, and there are about 5 other types of graphics cards very close in price to it that get much better performance. 750Ti is never a good decision to buy unless you are using a very very small PC case.
