hi, i hope this is the right section. for mainly the purpose of playing Second Life at a good FPS, i want to upgrade my 666mhz processor to something substantially beefier. i have been recommended to go for a 2.8 gig mhz one, and also told that dual core runs slower than non dual core on SL. i intend to go and get one from PC world or something and have them install it for me on site, but having had a look through ebay the prices seem to vary wildly (and thats even before a possible technician charge) what sort of price will i be looking at? (UK) INTEL PENTIUM 3 666 MHZ 1 GB RAM microsoft windows xp service pack 2 ========== radeon 9550 agp x4 / x8 cheers.
