The AMD A8 one will be better for gaming before you add a GPU and the Intel i3-2130 will be better after you add a GPU. Secondly you'll need to either upgrade the PSU in both to run a 560 (do you have one? because if not I'd say go for a 7850 1GB). If you don't want to bother changing the PSU then you'll have to go down to a 7750.
yes if you already own a gtx 560 then get the dell inspiron.
if you dont have the 560 yet then instead get the 7850 1 gb as andre mentioned along with the dell pc.
however you could also look at getting the hp pc and installing the 6670 in it if you want to save some cash since the hp pc supports amd crossfire with 6670.
also as andre mentioned if you go the 7850 or 560 route you MUST get a new quality psu as well
Awesome, most likely go for the 7850, thanks for the quick reply. Also would the i3 be able to run and record with fraps while playing or is that something the Amd would be better for?(since its a quad oppose to a dual) and could i get an honest opinion of this setup? for games like BF3 Skyrim lol...
I've only seen one on the forums so far where we discovered the OP didn't have a PCI-E x16 slot. It was a slim model e machine (which are junk first off). He was trying to run games on it and it's a desktop with the lowest of the low AMD CPU/GPU combination running at something like 1.6 GHz. Both of those ones should be fine. But since he never listed an exact model (say a link to the product support page) I can't be 100% sure but saying that I'm 99.9999% sure as it is.
