I've made a great deal on eBay.uk. I got 8 sticks of 4 GB RAM DDR2 FB-DIMM 800 MHz Micron Memory (small radiators) for 1/5 of price in Poland ! I've putted them in my Mac Pro 2006 (1,1) and in a few weeks I will transfer them to my Mac Pro 2008 (3,1). I've disabled SWAP file in Vista and putted Vista on Kingston's 40 GB SSD drive. It's flying ! After bootup it takes 2,5 GB RAM. With some simple apps like Firefox it goes up to 3 GB RAM.
