spec new PC

[tomto]

hi
im looking for a new gaming system, and have a limited budget of around £850 so im looking to get the best deal i can with that. im having trouble finding the right spec myself due to the many different types of things available, eg quad core or dual core.
im looking to play Call of Duty 5, WoW, and possibly crysis.
if possible id like to know any reasons behind the choices and whether or not i should choose Vista or XP (32bit/64bit)
im a novice so building a PC is out the question, and would probably end up breaking the full thing , so if there are any specific base units available from OcUK which are available and within the given budget i would be grateful for any feedback.
thanks in advance
Tomto

Will do what you want for your price range, it'll run most things these days but will obviously struggle with Crysis at higher settings.

The OS choice mainly factors around how much RAM you want, i'd go for 64bit for future proofing since it'll allow you to go 4GB +.

Quad core doesnt offer that much performance over dual core in games so that could be a money saving point, just for example check this lot, it's better than the pre-built with a monitor and 64bit Vista.
