I bought this Msi Cyclone Gtx 460 768mb 2 months back, now i'm planning to get another one...But I've heard that the 768mb memory will not be enough for future games.. I cant afford to get the 1 gb version now as im still a student.. So should i still go with the 768mb or reconsider going with another lower 5770 1gb crossfire,Gts 450 1gb or any suggesstion price lower than the gtx 460 1gb version.... Playing in 23" monitor 1920x1080 native resolution..
