Hi all, I've been looking for an upgrade from my X1650pro 512mb DDR2 card for a long time now. I've found an HIS HD 2600XT Zalman 512MB GDDR3 going for £39. I use my pc for photoshop, HD video editing and very light gaming. Should I settle for the 2600 or go for something else? And are there any Nvidia alternatives? Thanks.
