Get the GF3 TI200, its a cheap but Very Very! good card.
Cost are 60% of what the Regular GF3 costs But packs the exact same Power (once you tweak the Core and Ram mhr allitle and thats easy as Hell.
They even suply you with a app that does that.
I got mine at 260/521
Thats above the TI500 Speed (witch Costs double the TI200 price)
And beleave me, there's no beter card atm then the TI500, Dont gime that Radion BlaBla, Its drivers suck atm so there's my point.
Get a TI200 and you will be a Happy Gamer for the next year (or 2)
