my 9250 se gives 3645 3d marks.may be a tc one.

what is a TC

TC -> Turbo Cache ..... it is a tech. by which the gpu is able to share system ram via the pcix architecture when its video memory runs short ....

And the 9250se is a Radeon card ... no way it can support TC ... only the newer low-end pci16x cards like the X300 from Ati can use a similar method termed Hyper-Memory for the Radeon series ....

and i got 3066 3dmarks(03) by running the test on 800x600 mode.

only bench ur rig at default settings ....

my frnd went to purchase 6600 grafix card but he found many variants like
gainward 6600 gt, MSI 6600, XFX 6600 and two three more.

what is the difference betwwen all the above cards, do the performance of the above cards differ? If yes why so , cause all these cards have same graphic procc.?

Here's a bit of info on the 6600 variants :

6600
no. of pixel pipelines : 8
core clock : 350 MHz
mem. clock : 500 MHz
video mem. : 128/256 MB
mem. type : ddr
mem. interface : 128 bit

6600GT
no. of pixel pipelines : 8
core clock : 500 MHz
mem. clock : 1000 MHz
video mem. : 128/256 MB
mem. type : ddr3
mem. interface : 128 bit

So a 6600GT is better than the 6600 in actual performance ..... different companies sell similar cards ... i.e. similar cores ... with their own tweaks if any ....
