Alright well I'm a bit confused with all of these new video cards being released and I need someone to clarify a few things for me lol... I'd like to know what is for example the difference between a 7800gt and a 7900 gt, is there a big difference between them? Is the 7900 gt a replacement for the 7800 or is it just an upgrade? It seems the 7800 is not being sold anymore, was there something wrong with it? Are they going to do the same with the 8 series, release an 8900 card? or was it an exception? Also I was wondering what's the point of the low end cards like the 7300, 7600 etc... Are they better than say a 6800 ultra?
