Hello all,
I have recently added a 7870 to my PC (old GPU was a 9800GT), but in games such as Bad Company 2, Team Fortress 2, and Killing Floor, I have noticed quite a CPU bottleneck, with TF2 and Killing Floor dipping from ~150FPS to around 35 with lots of enemies on screen. This is quite troubling, but I kind of expected a bottleneck to manifest itself. I have verified that it's the CPU by trying BC2 at a much lower resolution, with its frames per second staying the same at around 45 FPS.
Here are my current specs:
CPU: AMD Phenom II X2 550BE @3.6 GHz, might OC it harder at some point
Motherboard: Gigabyte GA-MA785G-UD3H
RAM: 4GB OCZ Gold DDR2 memory (5-5-5-18, trc: 24)
GPU: XFX Radeon 7870 @stock clocks
I've been poking around the web, and I've been thinking about buying a Deneb online, and making use of that, since it seems my issue is more about the lack of availably threads. I really don't want to have to save up 400 bucks to go to an i5-3570k (or the AMD alternative,) since the alternative is getting a >$120 CPU and being able to roll games at >60FPS with that.
Should I upgrade everything, or can I save $300 and just get a quad core CPU? Thanks!
