I've got the opportunity, where I can sell my Geforce 4Ti 4200 64MB for R1000 (approx. $100) and buy a new Gigabyte Radeon 9600XT 128MB for R1900 (approx. $190). Do you think I should take it, wait, or leave it? So far I've been able to run my games at 1600x1200 at a pretty decent frame rate, but I'm worried about HL2 and Doom3. Any advice will be greatly appreciated.
