I have an older Gateway 700X and I need to upgrade the graphics card to run Adobe CS4, which needs Open GL 2.0 & Shader Model 3.0. I found an ATI card (ATI Radeon HD 4670 1GB GDDR3 AGP 8X) that will do the trick, but I do not know if my motherboard supports 8X. I think AGP 8X came out in 2002, and I bought my system in Dec.2002. I want to make sure before purchasing. Please advise. Thanks in advance. Bill
