Hi, just a quick guidance note on PC building.
Its all about getting the combination right.
Its a marriage of processor speed, memory capacity/speed and rpm of the hard drive, dont let a slow hard drive ruin an otherwise perfect system.
Make sure you research your GFX card too, dont buy into a high memory GFX card only to find that the GPU lets it down. Do the homework first.
Trawl the sections in here for advice.
Partition your hard drive and place windows only on the C:\
Store your data, files and programs on the D:\, that way if anything goes wrong with windows you can simply reformat the C:\ partition and all data, settings etc will be safe.
BACK D:\ THINGS UP TO CD/DVD ONCE A WEEK.
Try to get hold of a copy of mini-xp, its a cut down version with all the cr*p removed and can sometimes use only about 50MB of memory when running.
Do a CTRL ALT DEL after you close down all the background processes on normal XP and see what the memory load is to compare.
Tested mini-xp at work and its great, specially if the system is only going to be a gaming one.
Has no IE, no media player etc, but must stress only really for use as a gaming platform.
You'll need to add DirectX after install, altho I'm sure there's a version floating around with it installed less the usual garbage.
You'll find it on torrent, Limewire etc.
Finally other things to note:
Get a low memory usage firewall, stay away from Norton.
You're safe to close down your Anti-virus packages while playing AH but you will always need the FW running.
One really good, low memory, FREE anti-virus we've tested which has a very very small memory footprint and high scan speed is AntiVir, free and excellent for home usage. Has all VB100 awards recently and costs nothing.
Firewall cant really go wrong with ZoneAlarm basic, free and easy to setup.
Hope this is of some benefit to you.
