CPU/GPU Balance with e5200
I currently have an e5200 processor (overclocked to 3.3GHz, 266x12.5) and an aging Radeon 3850 video card. I bought a crossfire-compatible motherboard with the intention of eventually using it, and I am considering buying a pair of 4770s or 5750s. What I'm unsure about is this: will my modest dual-core processor bottleneck these cards?
Take a look here:
Even with the overclock you'll be looking at a HD5770/GTX260 class of card at the most, anything more will simply have too much performance to be used with your CPU at that resolution.
As for Crysis, one big help will be to turn the physics down a bit-it uses a LOT of CPU power.
If you want to replay Mirrors Edge and play Batman AA you might be better served with an Nvidia card- both games use PhysX to good effect.
