Graphics card offers are coming thick and fast as the new pricing and cards loom closer. This is the upgraded GTX 260 that beats the 1GB Radeon 4870 in a decent number of tests now (the original one didn't really contend). Whether you buy this or the 4870 depends what games you play, have a look at the reviews on line for more info.
Pretty sure this is the best price for a 216 Shader Core GTX 260, the standard one can be had for much less. Free delivery is available at OCUK forums but will take a bit of participation.
Please note this includes Free full copy of Far Cry 2 and a 5 year warranty, not to be sniffed at.
