Dont get that psu, I had one of those before and even though it all looked good on paper I had many issues which buying a better psu fixed. Pay the extra £10-15, it will be worth it in the long run. These ebay sellers are also unreliable, look at the wattage in the name (650w) and then read the specs below (600w). http://www.ebuyer.com/product/127861 regarding the gfx : 1. I would avoid buying it from ebay as you might have issues if theres something wrong and you need to rma (personal experience). 2. I would avoid anything with less than 512mb but if you have a tight budget than buy the 8800gt 256mb as for an extra £10-20 youll get a card thats around 50% better. http://www.ebuyer.com/product/139107 (cheaper) http://www.overclockers.co.uk/showproduct.php?prodid=GX-128-LT&groupid=701&catid=56&subcat=1008 (better service/ support) Edit: I assume you have bought them, you can still change your mind and fill in a mutual agreement form, this way the seller gets his advertising cost back. In most cases they will agree as its easier than persuing a non-payer and losing they original cost.
