After deciding to update my studio system to a multicore, I did extensive searching to find the best price for PC`s.
Looking at both building my own machine again and sourcing best prices for good parts, or best pre built machine prices.
I recently bought an incredibly high spec quad core machine for stupid money.
A machine that would normally cost in the region of 700-900 quid
I got for 350
All the parts are good spec too.
I simply couldn`t source the parts cheaper myself.
Heartily recommend them so if you are looking for a new desktop, try these guys

But look at their ebay auctions as you can get their stuff even cheaper than on their site if the bidding is good.
