thanks hopefully with as much spec as possible and amd processor or whatever is best 
hi henry,possibly the best gaming p.c,s for less than £1000 are mesh computers
for example the mesh Elite Express Quad (http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTVIEWPAGE&USG=PRODUCT&ENT=PRODUCT&KEY=221594)is a amazing p.c considering its £1000 price tag
with a Intel® Core™ 2 Quad Q6600 Quad Core Processor(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51257&POPUP=1) and 4GB DDR2 667MHz Memory(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51240&POPUP=1) this is more than enough for any gamer,i mean 4gb of memory,and with a 256MB nVIDIA GeForce 8600 GT graphic card(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51258&POPUP=1) this p.c will play any game you throw at it,remembering the 8600gt has direct x 10 and pixel and shader model 4.0 capability
storage comes in the shape of a 500GB Serial ATA Hard Drive with 16MB Buffer(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51241&POPUP=1),and your display is a 22" Widescreen LCD TFT Digital Display with internal speakers(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51242&POPUP=1),however dont worry the actual sound system is a Creative Labs T6100 – 5.1 Speakers with Subwoofer(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51245&POPUP=1)
optical drive is a LightScribe Super Format 18x Dual Layer DVD Writer +R/-R/RW/RAM(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51244&POPUP=1)and the dediacated sound card is the excellent Creative Labs Sound Blaster X-Fi Xtreme Gamer Sound Card(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51234&POPUP=1)
finally all of this amazing hardware is based around one of the finest motherboards avalible the PCI-Express Mainboard – SLI nForce 650i SLI(C55)(http://www.meshcomputers.com/Default.aspx?PAGE=PRODUCTDETAILVIEWPAGE&USG=PRODDETAIL&ENT=PRODDETAIL&KEY=51256&POPUP=1)
all this for £1000 is what i think is a bargain,and to round this off they even throw in a 2 Years On Site Service ,meaning they will fix it in your house!
why not take a look at the rest of the range…http://www.meshcomputers.com/Default.aspx?PAGE=MAINPAGE_VII
hope this helps
good luck henry!
