Well I think it is time to upgrade. I have been using ATI cards for quite some time now, ever since mx420. I was thinking of getting a x1800xl, but I see that 7800gt outperfoms it alot of the time. Besides the HDR+AA what features does x1800xl have to make it "better" than 7800gt? My budget is $600 (I also need to buy a mobo). Iwas looking on the egg and I can get 7800gtx for $450, should I just go with 7800gtx? My main question is: Why should I pay almoust $100 more for x1800xl? If most benchmarks show that 7800gt/gtx will outperform it, does it has some features that 7800 doesn't?
