I think it's about time I update my 4890HD with something newer. This is going into a 3 year old computer with an Intel i7 920 and 6GB of memory, so it all doesn't have to be cutting edge.
I'm thinking about:
SAPPHIRE 100314-3L Radeon HD 6870 1GB 256-bit GDDR5
EVGA 01G-P3-1370-KR GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5
Gigabyte GeForce GTX 560 Ti 1 GB GDDR5
- $224.99 a little over $200, but might be worth it.
I hate ati drivers....
gtx 560 ti for $219
Also upgrade your ram to 24GB for only $110!
I have the exact same system as you and I am in the process of upgrading as well. Just got the memory, now graphics card next. Currently running two 4850's in crossfire.
