I'm running TF2 on my good old ATI X1900 XT (512 MB RAM) on an E8400 with 2 GB RAM... and IIRC I'm running on 1600x1200 and pretty high details. It looks fine for me... never have measured the FPS (What's the command for that?) and according to Computerbase.de your card is around 1/3 of speed compared to mine.
If you wanna get something cheap, look for one of theses cards with the best price-fps-rate:
ATi Radeon HD 4830 - 80 €
Nvidia GeForce 9800 GT - 85 €
Cheaper:
ATi Radeon HD 3870 - 65 €
If you wanna spend some more to get a decent card for the next games:
ATi Radeon HD 4850 - 115 €
Nvidia GeForce GTX 260 - 140 €
ATi Radeon HD 4870 1GB - 150 €
Here is an overview:

performance rating
It's in German, but I think you'll get the funky colored graphs (Preistabelle = prices in Euro, Preis/Leistung = price / fps).
Comparing your card to newer cards:
ATi Radeon HD 3870 is 7 times faster
Nvidia GeForce 9800 GT is 8,4 times faster
ATi Radeon HD 4870 1GB is 12 times faster
