Just from experience with the forums, it is not worth investing more into computers like these. If you do invest in something make it worthwhile, so choose something decent that you would want to be incorporated into your next build. As for your next build consider these parts for two different platforms.
A suggestion build - AMD
AMD FX 6300
GTX 750/GTX 750Ti/R7 260X/R7 265
Gigabyte 970A-UD3P/Asus M5A97 R2.0
Case - personal choice
HDD WD Blue/Black 1TB (Black is better, you may also want to use current drive and change it over)
RAM - G-Skill 8GB Ripjaws 1600Mhz 4GBx2 DDR3
Intel -
intel i5 4570
ASRock H97 Performance
(everything else stays the same)
This intel system will be more expensive then that of the AMD, but is a more...
