I put together a computer to have at my dad's house with one of my HP vectra vl800 with a 1.7ghz p4 and 512mb ram. I currently have a Radeon 7000 64mb (I stole it from my cousins computer i made for him using one of the same motherboards, replaced it with a 16mb Nvidia RivaTNT2,) Soundblaster 16 sound card. I tried to install FarCry on it, but it somewhat runs it on the lowest possible settings. Then i also tried Painkiller black edition, and on lowest setting that was very choppy. So i was wondering, if i put this in it, http://www.newegg.com/Product/Product.aspx?Item=N82E16814121260 , would that perhaps boost the performance? It uses PC800 RDRAM, and supports 2gb according to the manual, but even 1 gb of RDRAM on ebay is outragously expensive. I also think some of the performance is robbed from overheating. The processor heatsink has increadibly small fins, covered by a fan, but the space between the fins is too small for any airflow, so hot air just builts up underneath the fan.
