First of all: great site! Google has led me here a number of times. Hope this is in the right place.
Anyway, my issue:
I bought a 2nd-hand PC recently with the following specs:
Windows 7 Professional 32-bit
ASUS M3N78-EH Motherboard
AMD Phenom 9550 Quad-Core Processor (4 CPUs), ~2.2GHZ
ASUS ATI 5850 1g DDR 3 graphics card
4GB DDR2 RAM
This system is giving me simply horrible performance in all the games I've been playing. In Starcraft 2 I can get 50fps on medium idle in a 1v1 which drops very low late game; In a 2v2 I drop as low as 6fps in the mid-late game. In League of Legends I get about 55-65fps idle at the start of the game which drops to about 25-30 once battles start, all on low settings. And in Battlefield: Bad Company 2 I get around 20fps on low settings.
I have updated my graphics card drivers, audio drivers and chipset drivers. I've downloaded HWMonitor and found no overheating. Today, I ran 3DMark06 and got these very poor results, however I do not understand them: http://3dmark.com/3dm06/15772022
Does anyone have any idea what exactly is the issue? Have I been scammed or can this be easily remedied?
Oh ok, that would make sense. I have also noticed from task manager that my CPU usage is always low so I guess that's why. Would this also explain why things such as live streams are very slow and laggy for me, even though my internet is good enough (can watch it on my other machine)?
Is it correct of me to infer that your post means my graphics card is fine? And a new mobo would improve my performance back to what it should be?
