Just remembered
I've got a 128 Mb Gigabyte 6600GT card that's a couple of years old knocking around.
Would that be better than my couple of months old 512 Mb 7200LE card?
And by enough to be worth the bother of swapping them around, uninstalling the 7200 drivers and installing the 6600s?
Incidentally, ordered the RAM about 9pm Thursday from Overclockers and it arrived on Saturday - impressive

Haven't had a chance to pop it in the PC yet though.
