The 6450 is now out, and newegg has a few to choose from. I need a card to replace my 2600xt, and I want something that I can play 3D bluray with. I tried a 430GT, but I returned it because no matter what I could not get rid of the stuttering with recordings. I have read some good things about the 6450, and it sounds like it should be all I need. I know this card is only 64-bit, and it comes with GDDR3 1gb or GDDR5 512mb, but for HTPC will it matter that it’s only 64-bit? The 6570 is a little more, but is there any benefit to getting that over the 6450. I won’t be playing any games on the HTPC.
