amd a8 5600k and amd 10 5800k how much gap?

[cherrydee]

i know amd 10 5800k is much powerful than the a8 5600k but how big is the performance gap? I'm on a tight budget and i play games usually at low-mid settings only. online games, skyrim, cod, bf, crysis but i'm fine with low settings

additional question:
for mobos, how much performance gap is there between a55m and a75m chipsets? the latter having usb3.0 and HDMI port

The motherboard doesn't affect performance. Some chipsets/boards just have more features than others (USB3.0, HDMI etc).

Here's a thread about the difference between the CPUs: http://www.tomshardware.co.uk/answers/id-1669035/amd-5600k-a10-5800k.html

I would still stay away from APUs, even if you are fine with playing on the lowest settings (they get outdated fast and the FM2+ is practically non-upgradeable.)
