After owning my Mac for a year I thought I'd never look at a PC again, until about a week ago I wasn't but now my brothers emigrating away he's left me a big white tower 'gaming' comp for me to get my kicks on Flight Sim (sad i know) and Halo on Steam. - Does the last bit make sense 'cos I ain't got a clue what it means, its just what he said to me!
Anyway, I'm new to this stuff so I suppose I'm sort of asking for a 'rate my system' and what can I do to improve it.
It's running Windows XP, Pentium D 3Ghz CPU with (now) 1Gb of RAM. It was running 2Gb extended but something went 'tits up' on start up and pulling the extra RAM bar cured it.
The Video card is 'beefy' as he put it, details are Nvida GeForce 7600n GT. So I don't believe I have to do anything there. The sound card is also pretty sufficent for what I need.
So suggestions please as to what I can do to pimp it. He suggested a new case might be an idea and also a USB card as the motherboard ones are a bit, well, shit.
As you might be able to tell, i know jack all about PC, so any help greatly appreciated!
