Zalman make some good products that is true. Recently I've always gone with Arctic Cooling products for heatsinks because they seem to perform very well for their price.

For PSUs the best you can buy is meant to be PC P&C PSU's.

The main thing to look for when buying a PSU isn't actually the total Wattage they can deliver, but the Amp rating on each rail. And for modern PCs it is better to get a PSU with a single or two +12V rails instead of 4 or 5. This is so that the Amps being supplied can be delivered on that single rail, instead of being split between them all, meaning one rail only gets about 20A.

For the GTX285 it needs up to 40A on a single rail, so Teho make sure your PSU can deliver that on a single rail. You should however be OK if you delivers at least 20A though, but more is better.

But definitely take a look at the ATI Radeon HD 4890 1GB cards as they are powerful cards for the money. Or for the most powerful ATI card look at the 4870 x2 which is a dual graphics card like the GTX295, but still cheaper than the GTX285. And ATI graphics drivers are now very good, but you will still find some people saying they won't buy ATI because of the drivers.

BTW, if any of you need some advice on current PC hardware just ask. I try to keep up with current PC hardware so should be able to give a few tips. I never like to pay over the odds for PC hardware so am always looking for the best value for money for the performance hardware delivers.
