not asking for myself, my mums partner owns said machine which he has had for years and im just checking it out to see if i could improve it for him as he wont let me build him a new one lol and also hes saying its getting warm. anyways i know about dell and their propriety setups, but equally i know some dells can be upgraded and wondered if the xps was one of them? was going to suggest my evga as i havent sold it and its just boxed doing nothing as the tower uses atx rather than those that use the longer units, but obviously this isnt my computer to do as please. core2quad viv q6600 4gb ram ati 2600 xt wifi card sound card couple hdd's optical is all it consists off, but i want to make it faster as he says its slow which is expected if you excluding whatever on drives, so im looking up ram to max it at 8, going to put my GT610 in it maybe to see how that does as hes a train fanatic, so model railway building in shed, designs on computer, he likes train simulator. at the same time i have tried to convince him to give it me if i sort him better lol.
