ATI graphics major problemo. Nvidia is vice versa but still a problemo..

I didn't say the ATI hardware suks but the the graphics are very not so realistic in rendering. Color too strong and still jaggy despite having to turn it to the max. However Nvidia is vice versa, its graphics are very much realistic in rendering and color but the hardware are very fragile to heat and overloaded GPU/RAM. Throughout my entire life i have my first respect to ATI graphics in the late 90's when DX7 was very much hardware utilized for soft render without TNL. Then came NVIDIA TNT with TnL with more life like graphics. Until present day i've burned 6 pieces of NVIDIA graphic cards just because of rendering my 3d works, i did not even Over Clock for gaming yet...actually i hardly play any games. However no hardware failure problem for ATI just the poor graphics i have to live with it. My last project rendered with Nvidia was "EXAGE" models, everything before it also have smooth render and in game looks..perfect Anti-aliasing. "XAVAGE" project was on ATI hardware....yes you can see all the rendering and screenshots isn't on par with Nvidia render as you can compare from several screen shot from my projects. ouch!
However I would thank to ATI today because the still making AGP slot support for older pc which is now i'm survive because of it. If i'm loaded with huge budget i'll get back to Nvidia
