ok so with the new series of games coming up I am getting a little worried about my pc's ability to handle a few of the games. my graphics card is a Galaxy GTX 460 1 gig SE. I know there is potential for overclocking on it but how much? I have compared the card to one that is recommended for bioshock infinite I don't see much of a difference. my gpu runs at 700 where as the recommended runs at 800. can I achieve this with my gtx 460? or is there a low budget card to replace it with that can do it? I have 100 to spend on a new one. also I noticed that my card is a 256 bit interface and so is what the recommend. does this mean no 128 bit interface can run it?
