I can get the VTX 2gb version for 260, or i can get the more reputable manufacterer, saphire for the same price, however it is only the 1 gig version. I could also get a powercolour for 200, 1gb version. I have heard the VTX use dodgey components to cut costs. Don't know how true that is however.
OP has already decided on a brand. ^^^^. the 1gb is sapphire or powercolor. sapphire is the one i would go with tbh
