hey anybody, could you help me out a bit? im thinking of upgrading a couple of things but i'd like to know what kind of performance difference ill see. if its low, i dont think ill upgrade. currently i have... T-bird 1.4 ghz 512 PC 100 crucial ram and all that other junk. i want to get... Athlon XP 1800+ (then overclock) 256/512 mb PC 2700 ram MSI KT3 ultra mobo? just give me some ballpark percentages for what kind of performance gains ill get. right now i think my main bottleneck is my slowwww ram. thanks!
