Here is my current spec :

A8-5600K 3.6Ghz
Gigabyte F2A85X-D3H ( FM2 )
ASUS HD 7770 DIRECT CU TOP 1GB DDR5 128BIT
Cooler Master GX Power 550watt 80+bronze
Plextor M5S SSD 128GB
WD 1TB 7200RPM HDD
Samsung DVD Writer
Corsair Vengeance 1600Mhz 4gb x 2
Monitor LG Flatron w2043s 1600*900 ( LCD )

Problem : Playing crysis 2 and battlefield 3 cannot over 60fps

But below spec can reach 80++fps with 4AA

A4-3300 2.5Ghz
Asus F2A75-M LE ( FM1 )
ASUS HD 7770 DIRECT CU TOP 1GB DDR5 128BIT
Cooler Master GX Power 550watt 80+bronze
Plextor M5S SSD 128GB
WD 1TB 7200RPM HDD
Samsung DVD Writer
Corsair Vengeance 1600Mhz 4gb x 2
Monitor LG Flatron w2043s 1600*900 ( LCD )

a few things are possible, vsync, which limits it to 60 (or 120) no matter how fast you computer is.
or the rig cannot really reach >60 since it is either not fast enough or the game is just to heavy.

the other rig, make sure the settings are the same, and the resolution. otherwise it is not a fair comparison.

and there's no way a 7770 can reach >60 when in 1080p at high settings, my old 560Ti can only achieve that when in med-hi (mostly medium). if you have maybe a 660Ti or higher, then yeah, ultra settings even

That is called V-Sync, and is there to prevent an issue called screen tearing. Which is where you get multiple frames trying to display at once, which causes these lines. The reason why its 60 and not some other number, is because that's how fast most monitors can refresh. So even if you had an FPS above 60, your monitor couldn't display it because its simply not fast enough.

This is a somewhat exaggerated example of screen tearing, but you can see whats happening.

This video will explain a bit, though its more a showcase of Nvidia's adaptive V-Sync technology.

Nvidia doesn't own V-Sync, just there's a few issues with V-Sync that Nvidia fix on their GPU's, and they call these fixes Adaptive V-Sync. Nothing to do with PhysX.

The hardware used has no impact as to whether V-Sync applies or not, its a setting that's either enabled in the game or graphics driver.

You could change the PSU and GPU to that no problem, but I dont see the point as you going to be limited by the weak CPU performance of the A8.
