I second that vote for a Sapphire 9800np. I too got the Samsung 3.3 version (only from allstarshop.com) for $250 plus free shipping. I have it running stock HSF @ 400/350 boot with no artifacts or issues of any kind... I didin't even have to flash to the Pro BIOS. It's amazing how solid this 3.3 RAM is at 350.
If you buy the 9800np, you owe it to yourself to install the newest Omega hacked drivers (based on cat3.6). No soft mods, no messy volt mods... Just use the included Radclocker to bump that sucker up. It's so easy and painless to OC this card, you have no reason NOT to... I'm not a numbers and benches kinda guy, but I noticed a huge real world gaming improvement over the stock Cat3.6 and card out of the box at 324/290!!!
