Hi everyone,

I recently purchased old pc parts off two friends. I watched these parts working in action before I purchased them. The CPU (AMD Athlon ii X4 630 2.8GHz) and motherboard came from one friend who ran a GTX660 with his setup, his setup could run Battlefield 3 at 60+ frames on BF3. While the person I bought the GPU (AMD Radeon 4890) ran his setup with an old DDR2 motherboard socket intel cpu, and his setup ran Far Cry 3 at high running just over 30fps.

The CPU never had any framerate or stuttering issues with a GTX 660 which is alot more high end than a 4890. The 4890 also had no issues with the old as hell cpu it was using. So I decided to buy these parts.

To my surprise when i first started to play after I downloaded my GPU drivers my computer had a bottleneck effect. It struggles with CS GO, BF3 and lots of other games which is odd.

I have asked my friends and they have no explanation for this so I have taken this to the forums in hope of help. Any advice would do.

Cheers
 
Solution
your cpu is too weak. Get say a fx6300 with motherboard eg gigabyte ga 970a ud3

4gb ram isn't helping - try 2 x 4gb

a generic power supply won't help either. Check if the vol,tages are with in 0.2v of 12v, 5v and 3.3v in biuos/uefi. If not, try a Seasonic 620, XFX 650 or Antec HCG 620M. You should have at least 600W for the hd 4890 anyway.

Also check cpu and gpu temps. If cpu is over 40C or gpu over 65C then that will slow your pc down.

So - lots of problems.
CPU: AMD Athlon ii X4 630
GPU: AMD Radeon HD 4890
RAM: Kingston 4GB
Power Supply: Generic 550W
Case: Irrelevant
Motherboard: Gigabyte AM3 Motherboard (Will open and have a look)

So you've been told what the issue might be and you've completely ignored him...
