Nice post Andre, my wallet is groaning already :) - currently watching BBC
HD via my onboard 8300 which can only manage Temporal x1 smoothly
(sometimes x2 on some recordings). I have a 8500 GT (only 256Mb) waiting
for me to collect from the post office at lunchtime so will see if this
offers me any improvement. The GT 210 looks like a good alternative for
those of us penny pinchers ;), I see these cards both have the 40nm 216
cores from the GTX260 as well.

8300 results for those interested (ASUS M3N78 Pro Motherboard) -
