Crossfire HD 3650 or HD 3850/70?

post #1 of 7
Thread Starter 
I've just got a Pentium D 840 w/ a Crossfire enabled mobo, ECS 945P-A ver. 1.1. It only support Netburtst CPU, or I would've got a C2D already.

The 2 PCI-E slots runs at 16x and 4x.

Which will perform better? HD 3650 Crossfire GDDR3 or a single HD 3850 512MB?

Or should I stick with Nvidia? And remember, this is a Pentium D @ 3.2GHz, it's not C2D, it might bottleneck the GPU.

EDIT: Yes, I'm going to OC the Pentium D

I'd say just the single HD 3850 would be a good choice for that machine. The CPU wouldn't bottleneck it TOO horribly if you overclock her a little .

I'm doing a very similar setup here soon with a 945p chipset board and a PD 925. So I know what you're dealing with .

Yeah, a single card would be better. Crossfire/SLI with budget cards is a waste.
