shimmering on the nvcards has mostly been fixed; with adjustments to driver settings it was possible to eliminate it for the most part. it's possible that since the whole fiasco came to light, the default driver settings are now such that for the most part it's not as glaring an issue as it once was. shimmering was a problem for me with my 7800GS.. ati cards also had the same issue, tho to a much lesser degree as their default optimizations were nowhere near as aggressive as nvidia's.
still, texture filtering is so much better on the r5xx series than the g70/71. while ati's aa is arguably not as good (g70 shares the same AA as g71), the difference is nowhere near as glaring as the gap in texture filtering. having had both, there really wasn't anything about g70/71 i preferred over r5xx.
i must say tho, after running a g80 for the past weak my preference has changed from ati to nvidia; nvidia nailed it in 3d image quality (for whatever reason i'm not as comfortable with the 2d as i was with ati, but it's still quite decent - may not even be a case of which is better, rather just different and i was accustomed to one and need time to adjust) as they dramatically improved the texture filtering over g71. the filtering is as good as ati was, and the quality of the textured themselves are better than r5xx; kudos to nv for addressing those issues. i also have not noticed any texture crawl as i had in previous nv cards. overall i'm quite happy with my 8800 as they seem to have addressed everything i and many other had griped about with g70/71. performance (which is also very good) aside, it's still better hardware than my XT. thank goodness i haven't installed vista yet tho!
can't say i like their new nv control panel tho
one thing that kind of puzzles me however is the gfx chip partners. i've had great experiences with BFG support, and i've heard very good things about evga. 3 of nvidia's partners offer lifetime warranties (BFG, EVGA, XFX; perhaps more but those are the only one's i know of), while ati's products for the most part have only 1-2 year warranties, and while visiontek offers a "lifetime" warranty, it only applies to the "life" of the card; once it EOL's, the warranty doesn't exist... and powercolor has a similar "processing fee" as sapphire: "
Customers will be charged $12 USD (MONEY ORDER ONLY) for shipping and handling fee that within 48 continental states of USA. $20 USD (MONEY ORDER ONLY) for customers in Canada. (Pureto Rico, Haiwaii and Alaska customers' shipping and handling fee may be varied. (MONEY ORDER ONLY). If you have DHL / UPS / Fedex account, we would be happy to use that instead of the return shipping and hanlding fee. If you are not willing to pay for the shipping cost, please contact your seller."
very disappointing from that aspect....
