The updated list http://www.tomshardware.com/2007/1 [...] page2.html showing whats the best buy for certain price ranges was just made yesterday great timing!!. I just need to find out which cards can fitt in a Vostro 200 Slim Mini tower so I can slim down my choices.

(X1650 GT, Radeon HD 2600 XT, 7600 GT, GeForce 8600 GT) in order of personal preference.

The card is for a new system I wish to purchase. I am going to capitalize on one of the deals listed below the Vostro 200 deal is better as I don't waste money on a GPU I wont ever use! However space is an issue in the slim tower. Also I for the $150 dollar difference I can get a better card and wait for a deal on ram.

Thanks a lot FYI newegg has the 7900 GS's for 119.99 but comes to 99.99 with mail in rebate. An there are reports that the same 7900 GS's are on clearance at BB.

So it appears there is lots of flexibility in this $100 price range.

So now im thinking about the HD2600XT or the 7900 GS. I'm googling as we speak.

Thanks a lot you and the everybody else here have helped me out a lot with understanding key differences and helped me make much more educated purchases.
