Desktop Spec Help

[chrismscotland]

I'm pondering my next system and pondering either a laptop or desktop, I'm not too bothered about gaming but if I can get something that would let me run decent games for around £500-£600 I would be happy.
That budget does not include a monitor, operating system, mouse or KB.

Just wondering been thinking a bit more about building a PC rig, was considering a Mac but to afford something powerful I'm looking at a lot of money.
Would it be possible for a rig like this i.e £500-£600 to be powerful enough for Armed Assault 2?
