The AMD Trinity A8 and higher do deliver good gaming for the buck HOWEVER you do want to install memory in pairs to get the memory bandwidth up to where the games will be as good as possible.

My current system is as follows:
-Motherboard ECS socket FM1
-AMD A8-3870K (stock CPU speed but GPU oc'ed to 700MHz)
-4GB RAM 1600MHz
I don't plan to pay much and I want a medium-range gaming PC, I've considered either buying an entire new PC (this one is pretty new though) or just more RAM and a discrete video card.
Let's start with the video card, I've seen these:
-AMD 7750 for USD154
-AMD 7770 for USD185
-AMD r7 250 for around USD160 (I don't know about AMD r series)
-nVidia GT 640 for around USD150
-nVidia GT 650 for USD190
-nVidia GT 450 for around same price as GT 640
-nVidia GT 460 for USD180
-nVidia GTX 550ti for USD200
-nVidia GTX 560 for USD200
Also, if I only buy RAM + video card, do I need to upgrade my power supply for any of these cards? (using a standard 500w)
And that's the maximum I'm willing to pay for a single video card. Now moving to PCs, I'm willing to pay for:
-Intel i5 4430 (entire PC) for USD575 (with a HD2500)
-Intel i5 3330 (entire PC) for USD485 (with a HD2500) (is it worth the much higher price for the 4430?)
-AMD A10-5800k (entire PC) for USD476
-AMD A10-6800k (entire PC) for USD509 (is it worth the upgrade from 5800k to 6800k?)
Must remember that by buying the Intel PCs I'm going to need to buy a discrete video card (would have to wait for that)
What should I buy and why? I don't do much intensive gaming (but I game a lot) and sometimes I've to use virtual machines with Windows Server 2012 (in case you think my CPU isn't good enough for this)
