Is my CPU bottleneck to my GPU ?

Hi guys, just wanna ask if my CPU is bottlenecking my GPU. For the graphics card, I've got the Asus R7 265 2GB, as for the CPU, I've got the Intel Pentium Dual Core E6700 3.2GHZ (3.4GHz OC).

Now I know that my GPU is capable of running Crysis 3 on medium to high settings, but I set the game's settings everything on low, and even then I was getting some lag!(OK, a little more than SOME lag xD) I opened task manager, and while I was playing the game, I saw the CPU going up to 100%, and It mostly stayed at 98% usage!!! I opened HWMonitor, the temperatures that were coming out of the CPU were:

Core #0: 63C
Core #1: 57C

I think that I need to change my CPU (and I probably will). My main question is for the bottleneck, and my secondary question is what CPU upgrade would you guys recommend for me (which particular CPU) ?

Buy the most expensive CPU that fits your budget and that fits your motherboard. Crysis will suck up every cycle you can throw at it - that is why everybody uses it in benchmarking.

Hi,

You should consider getting core i5 / fx-6300 if you want modern gaming to be descent. Sadly Core 2 duo are out of date for new games.

What about getting an SSD, would I get better performance, for gaming that Is? Or should I stick with the CPU upgrade? If CPU, I'll be going with the Intel i3-4150, that's my budget, because I'll be getting a motherboard to support the new CPU :D

i think SSD won't help much , they are better for enhancing loading time nothing more .

Oh lord, no. If you upgrade your motherboard you change everything. Only if you plan to upgrade your CPU within the confines of the current motherboard/RAM configuration does my advice stand.

Once the motherboard is up for discussion, then you should look at RAM and ann the other stuff in conjunction. Figure out a budget and get back to us or only upgrade the CPU in a pin-compatible way with your current motherboard and save some money.

Well, my motherboard is relatively old, Foxconn G41-MXE, CPU socket LGA 775, and If I get just a CPU upgrade, It won't be that much powerful, 'cause It's a 775 socket, and I don't know any CPU's with a lot of power on a LGA 775 socket.

Therefore, I'll be upgrading my motherboard, so that I can upgrade to an i3 processor :) 

And here's what I'm aiming for:

+ Case: CM K380
PSU: CM B700 (already bought It)
CPU cooler: DeepCool Theta 15
Windows 7 Ultimate 64bit
