Hey everyone - I have a a pretty qick machine - 2.8 P4 on a Asus P4P800 Deluxe (800 FSB) with 1 Gig of Crucial DDR400 set in Dual line config. As a side point - if u guys have never tried Crucial, it is quite the good RAM - very overclockable, stable, and best of all, cheap. I currently have a Albatron Ti4200 Turbo, which has served me well but with Doom 3 and HL 2 coming out soon I think I have to set it free. I would like to replace it for around $150 US and was wondering if anyone could offer up their best picks for that range. I don't care about looks - I care about performance. I am not that much of an overclocker, so please take that into consideration as well. Now for the real question and the reason I started this thread - with the speed of my machine and amount of RAM that I have, do you feel it is necessary to have to go for the 256 version of whatever card I decide upon? Thanks in advance to all for expending your valuable time on yours truly.
