Thanks for replying gents i have an iqon industries putter with p4 processor 2.4 gig ,80 gig hard drive,256 mb ram,asus motherboard[P4S533-VM],19inc monitor and it all cost £800. only the motherboard only takes upto 4x graphics cards which is really dissapointing,so im really not sure wether to upgrade and get something built or just stick to what ive got.i use my pc for mainly surfing the web or playing games,although my graphics seem to be aceptable and i dont get any brake up or anything like that,i havent been able to check it against any other pc,s. anyway once again thanks for your time!!!:aok
