i7-2760QM Processor (2.4 GHz with Turbo Boost up to 3.5 GHz)
1GB AMD RadeonHD 7690M GDDR5
Would this do JRPGs well rendered at 1080p with 4X AA or more?
Depend on that JRPG (it will not for VP2, for example), but mostly yes.
Xenosaga, Grandia, Suikoden,DQ8 will NOT work well with that PC, they need more than 3,5 Ghz (and your max turbo boost will never trigger on PCSX2 since that 3,5 Ghz is for single core mode only)
The rest might have some better chances
just try it. if you think it did enough for you. that 2.5 C2D should equal a i7 on 2.4. that i7 might even be faster at the same rate.
It depends on how high it actually turbos. If the frequency is around 3.2Ghz or more, most games should run well.
Anti Aliasing is a problem by itself. In some games it works, in others not. Consider it a hack.
