I am thinking of installing a new graphics card on my Crosshair II Formula board (currently GeForce gtx 260). Can anyone advise if this would be the best option for increasing graphical performance. If so, what card would be compatible with bios version 2302? I have Phenom 2.6 9950 quad core cpu and 8gb ram. I understand this is an older system but just wanted to upgrade on the cheap before handing over to my son.
