Currently ive got a dell dimension 8250. everything is stock except for a ATI 9700 pro which i promply found did nothing to my gaming performance. (i play americas army, running on the UT2k4 engine, mostly CPU based) so the stock 2.4 Ghz intel and 512 mb of ram arnt cutting it. i figured id just add a stick of ram but nooo, sdram or w/e it is would cost nearly as much as a whole new mobo and 1 gb of ddr(1,2,3?) would. the stock 250w powersupply will need to be upgraded first i imagine, i figure ill just get a fortron 350-450 psu. after that im sort of clueless about the cpu, mobo, and ram. im sure i cant make a mistake going with any forum suggestions, so ill just go with what you think. i dont have too much cash, but im sure i can really boost my gaming performace without splurging $500.
