Solid state capacitors are better quality and last longer.
I don't like the 256MB 8800GT though. It tanks bad as resolution gets increased, sometimes starting at 1280x1024. Should have bought a 512MB GT or if that was out of budget, an 8800GS.
It's very cheap if you got this deal: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125089
But I'd rather have this (which was cheaper last week)http://www.newegg.com/Product/Product.aspx?Item=N82E16814130332
Take a look at this link: http://en.expreview.com/2008/01/21/review-palit-8800gs-384mb-768mb/?page=20
Dirt at 1280x1024 4xaa:
8800GS 384MB - 32.7fps
256MB 8800GT - 15.0 fps
The 8800GT leads alot of low res tests, but really both seem pretty equally playable. But once res and/or fsaa increases, the 256MB 8800GT falls of playable first.
Keep in mind, I believe the Gigabyte 256MB 8800GT has 700(1400)MHz mem like most 256MB versions.Still nice for $70 AR though, especially if you game at lower res.
