Got it on order at eBuyer, bumped down the delivery date until there wasn't a surcharge and it should be here Thursday
Reckon my card will be okay until then, it was pushing 90 degrees last night just playing RvS with no overclocking but didn't go any higher so as long as we don't get a heatwave (fat chance!) it ought to last.... (fingers tightly crossed)
Now just need to find something for 30 quid at Amazon. Crysis looks like an option
(even though I'll be playing it on a DX9 machine with settings turned down!)
