I have a two year old E-Machines C700a. I would like to make it as fast as possible. I have upgraded it to 256Mb of 100Mhz SDRAM, added a PCI (yuck!) Radeon 9000 64Mb, and an LG combo drive. It has a Intel Celeron processor plugged into a Socket 370 motherboard (as far as I know). I believe that these computers run a 66Mhz FSB (frontside bus). The other specs are irrelevant, since I cannot identify the manufacturer of the motherboard. All I can tell you is that it is based around the Intel 810 chipset, with two RAM slots, 3 PCI slots and no AGP (grr!). If anyone can let me know how far I might be capable of improving the processor without replacing the motherboard (I'm a student), I would be eternally grateful. I just wanta couple more fps out of my favourite 3D games, is that too much to ask? My concern is that the 66Mhz bus & socket 370 will restrict the number of Celerons I can go for. Thanks in advance.
