Sorry for the confusion. By casual gaming I meant occasional gaming. Bad english on my part I guess. So you are saying that I cannot play crysis 3 at all with fx 4300? But it says here
http://forums.anandtech.com/showthread.php?t=2302954 that fx 4300 gives an average of 48 fps which is not bad i believe.
Dude that benchmark is with a GTX 690(the fastest card available for gaming). When you are using a R7 250 just imagine what FPS you will be getting.
Here is a better review

"As for the Core i3, Pentium, Phenom II X4, and quad-core A8 APU, none maintains more than a 20 FPS minimum frame rate at the High detail preset.
Thinking that this might have been an avoidable bottleneck caused by our detail settings, we dropped the preset to Low and re-tested the Phenom II X4 and Core i3-3220. Even then, we didn't see minimums any higher than 25 FPS. The issue wasn't fixed in the recent 1.2 patch, either.
Our benchmark sequence does have that taxing bottleneck at the end of the run. But no matter how you process the data, processor performance is going to be an important consideration in Crysis 3. We can't recommend anything less than a Core i5 to gamers building a PC capable of handling this game, and serious enthusiasts will want a Core i7. Crysis 3 appears to be one of those rare games optimized for multi-core processors, as evidenced by the six-core Sandy Bridge-E's strong result compared to quad-core Ivy Bridge."
