The i3-2120 isn't a high end CPU, but it's a decent gaming CPU and probably the best that you'll get in your budget.
I wouldn't be too picky about memory, but I was pleasantly surprised to see such a great memory kit at such a low price.
Well, it's a case, no big deal about it. You're not using a bunch of high-power consumption components nor a lot of components and/or large components, so this case should do the job quite well.
This 7850 is about halfway between the reference 7850 and the reference 7870 in performance. It's factory overclock is that huge. It'll be an excellent card for maxing pretty much any game's texture settings out on a 1080p display.
This is a great little 500GB hard drive. If you want more capacity, then go for a 1TB model.
I just went with the cheapest DVD drive.
This power supply has plenty of power delivery for such a system and does so with good efficiency and a nice price.
Glad to help. Sorry it took so long, most of us Tom's guys (such as myself) are in the USA and we don't have a lot of our system building tools to work with when doing recommendations to your country, so we have to do a little more work to make recommendations.
No Problems. My country is still lagging a Lot in the "Build Your Own PC" Section!
Most of us Just buy whatever Branded PC's the likes of Dell, IBM, Lenovo are offering.
And i just hate those PCs. Charge too much for sub-par products. so, i decided to do this myself!
