Hello, first time asking here; but I'd like some advice on what to upgrade in my PC... I understand I have a massive bottleneck, but I'm not 100% how I should approach it.
Currently, I have:
AMD 7750+ (black edition, OC'd to 3.1ghz)
XFX 4890 OC 1GB
One 1TB ST3100340AS (7200RPM)
One 250GB WD2500KS (7200RPM as well, this is my windows HDD, games on the 1TB).
I understand the CPU is a bottleneck, and I have an AM2+ motherboard, and currently I do not have enough money to upgrade the motherboard on top of the rest.
Are my hard disks a possible bottleneck? Bare in mind I'm currently playing L4D2 (It runs well) and ARMA2 (Which I get fairly lowish FPS tbh), and BF2 PR mod (Pretty crappy FPS actually).
I've seen Phenoms which are fairly reasonably priced, but would I actually get that much performance from upgrading the CPU? Or the hard disks?
In the 'real world' those drives are about equal. Don't go flip flopping your installs expecting to gain ANY performance. There is no gaming bottleneck happening because of your drives. Its your cpu, thats it right now. You have enough memory that what needs to run during gaming is buffered in your memory.
I have an Athlon II 630 and a Radeon 4870 1Gb. I did some tests on the ARMA 2 benchmark with OCing my CPU and GPU. It was much more sensitive to CPU speed than GPU speed. The numbers were (roughly- from memory) CPU from 2.8GHz to 3.5GHz = 9fps increase. GPU from 770MHz to 865Mhz = 2fps increase.
So if you want better fps with ARMA 2, I would upgrade the processor...
