Not sure why there was an A10 in those builds, an APU, with a graphics card as well. This 740 is a dedicated CPU, leaving more processing power unused by graphics.

Better build for the budget definitely goes to Iron
 
With such a tight budget I would go for a Pentium G3258 as it pretty much beats the athlon in most games plus you have the option for an i5 later on where with the Athlon you're pretty much stuck

In my opinion, yes, it is, simply because it is a newer card and seems to preform slightly better. Also, it's a tad cheaper than what 750's are going for right now.

The 260x isn't a beast, but you will get Mid to High range settings on most games.
