Budget build for upgrading

[Onlinegamer55]

Hello people of tomshardware I would like to upgrade my computer for online gaming. It seems my cpu is a bottleneck for games even games it should be able to handle with ease on low settings lagg.

Current specs:
CPU: AMD athlon 64x2 dual core 3800+ 2x 2.0ghz
Ram: 4gb ddr2
Powersupply: CORSAIR Builder Series CX500 500W
VideoCard: Sapphire Radeon HD 6770 1GB GDDR5
Monitor resolution: 1440x900
HDD: 250gb don't know the brand.
OS: windows 7 ultimate 32 bit

The upgrade:
well i made a shoppingcard for in mine country (the netherlands) and i would like your oppinion.

I want to keep my videocard and powersupply because i think its good enough for most online games on mid/high settings.
I am also planning to instal windows 8 64 bit.
What i want to know is if the mobo and the case is good. I also want to have a small ssd just for windows and maybe 1 or 2 games. I am not planning to play games like BF3 CoD 3/BO2.
My budget is around 500 euro.
I don't need an OS because i already got it and I ordered a 32 inch Led tv and i am planning to use it as my monitor.

I do not know all that much about computer cases, but the case appears to be fine (good ventilation, etc.). The motherboard is another matter. My first (and only) experience with ASRock, was complete failure after a few months of using; even though all of their motherboards are not like this, reliability could be an issue. If the motherboard does work well (it most likely will), then it will be just fine.

This would be a better build to Max any game out there.
