Which is the fastest card?

[Executioner]

I'm having issues with my main rig locking up playing TF2, and I don't have time to reformat it (it's going on 6 years with the same XP install and hardware). You can imagine the programs I have installed, and it would take a full day to reformat using win7 and re-installing all the apps and settings. So I decided to use this rig, until it dies, as my business rig - web surfing, email, etc.

I do have another rig running win7 x64 with 4 gigs of ram. The card I have in there is a ASUS HD 5450.

I have the following spare cards:
1. Radeon X1900 XTX
2. Radeon HD6670
3. NVIDIA EVGA GTS 450

The only game I currently play is TF2, and I'm sure the Asus HD 5450 is not the fastest card. Which would be the fastest spare card (fps) to use based on playing TF2?

GTS 450 should be the fastest... definitely not the x1900 which is ancient.

Mines XD


but seriously the GTS 450 is the fastest

The 450, is about 25-30% faster than the 6670.
Its the fastest of those cards.

Thanks guys for the feedback.

6670 DDR3 or DDR5?
450 DDR3 or DDR5?

but the 450 is normally faster,
as for TF2, when I used to play that game some crashes were solved by disabling multi core rendering, deleting and downloading the game files again, running in windowed mode...
