I dumped my GF4 Ti4400 yesterday. Not that it had any major trouble with any game.... just the fact that I felt the price/performance of a Mobile Barton and a 9800P was right for me. My 4400 had a bit of trouble with X2 The Threat at 2048x768, everything disabled... it even struggled at 1024x768 as well, although I am finding that my 9800P does struggle with it as well at times with all options on. Particles seem to kill even my 9800P on NFSU at 1024x768, all on (except blur and light trails), x4 AA, x8 AF.
I probably should reformat though. Some games havent always agreed with me when I say my barton was stable and as a consequence, Win XP looks like Swiss Cheese.
I intend not to touch any component in my PC for at least 12 months. It probably wont happen though.... some fan is bound to die on me or ill decide i need a bigger case since it took me ages to wiggle my backplate in when fitting my NF7-S in.
