Em... well down on writing my rig looks pretty gaming freindly but recently ive been having an unexplained drop in performance so i am going to upgrade one part of my system, with a budget of 400Euro (roughly 450-$500). Now keeping in mind that the purpose is to improve gaming performance what do you guys recommend i buy? Ive been looking at either this RAM http://www.komplett.ie/k/ki.asp?sku=313461 or a soundcard, i was thinking mabye this, http://www.komplett.ie/k/ki.asp?sku=312206 (using integrated at the moment). Also i was thinking of getting an Athlon 4000+ or x2 4200+. So the thing that i want completely nutralized in my games is the dam jerks i keep getting if that helps to narrow down my hardware need... Anyway so what one new piece of hardware should i upgrade out of my System? thanks.
