Hey im building my own computer and im wondering which is better:

1. Gigabyte ATI HD 5870 PCI-E 2.0 1GB 256-bit GDDR5, 850/4800MHz

2. 2x|GeForce GTX 285 1GB

Thanks everyone

P.s.
Motherboard: P6T Deluxe V2
CPU: Intel I7 920 :P
Memory/ram: 6-8gb Corsair Dominator

Well when running 2 HD5870's the GTX 285 is only 10 percent slower. Therefore, running 2 GTX 285's will be around the same performance possibly a bit faster than only running one HD5870. But if you can I would recommend saving up to run 2 HD870's!!!

Make sure you have a quality 850W PSU for running two GTX285s, and we recommend a ~1000W unit for two HD 5870s (the Corsair TX950W would be ideal for either actually, but I haven't seen one for sale yet). Either card alone will thrive on a decent 750W PSU.

Taken by themselves, a 5870 is a lot more powerful than a GTX285. Two GTX285s would probably outperform a 5870, but would be expensive, require a high-end PSU, and would only really shine on extremely high-res monitors.

Yea a single 5870 would be best.
