There is no real big difference (cut the fanboy crap which is going to start under me) between AMD and Intel, I've got a AMD computer myself and I haven't got any issue. AMD had the last period a shit period with his market status and their products, right now, they're getting better then Intel with their 6 cores while intel (except the Xeon series, which are expensive) still has 4 even with their latest generation I7 (overpriced, can get a same CPU at AMD for 100$ less). So no.
Anyway, you can do the cooler later indeed.
*yawn*
I suggest you take a good look at Gandalf's post Cane, he explained it all.
If you want to create a gaming pc, go for the one which has more graphic memory, as in 2GB instead of 1GB, as games like GTA 4 require more memory than a better processor. Also GT650M is the cheapest kepler in the market. And that extra 1GB, does make a huge difference, consider getting a 2GB DDR3 NVIDIA GT650M, since GDDR5 version makes very unnoticeable difference.
I have the GT650M DDR3 one in my laptop, and I'm yet to find a program which it can't run or lags on it.
