GPU bottleneck or just bad hardware?

ok so i bought the MSI N760 HAWK as well as a 650W PSU to power that beast.
i have installed everything well and all cables went in the right place the first time (also my first time messing around with that), so after installation i installed the driver wich came on a CD with the package... after the driver was installed and w7 was rebooted i started bo2 to test my card a littlebit (since i knew the fps i could get on my other card it seemed to me as the right choice..) first i putted everything on high and resolution on 1050p and i found out i get a 40/60 fps on nuketown (one of lower detail maps of bo2) then i putted everything on low and putted resolution on 738p or something in that manner and still got 40/60fps, i also get laggspikes every 10 secs or so...

do i need to install hardware or is my gpu bottlenecked by, cpu and motherboard?

specs:
650W PSU
Intel Pentium E5300, 2.8Ghz
MSI N760 HAWK
500gb HDD
Gigabyte EP31-DS3L
4GB RAM 900mhz

thanks for the help

He's right, that E5300 is heavily bottlenecking that 760.

Unfortunately you'd need an entirely new CPU, motherboard and RAM to take advantage of the 760's capabilities. The E5300 would bottleneck even a GTX 650, let alone the 760.

An i5 4430 and a B85/H87 motherboard and 8GB DDR3-1600 RAM would do wonders, for the moment that 760 would run as fast as a 650 on that setup.

Lowering the resolution puts more load on the CPU, so that would explain why you got those frames at the lower resolution as well.

thanks finally some good help:
im getting an intel i5 4670k with z87 motherboard (i think its that 1)
im also getting 4gb of 1600mhz ddr3 ram and ill upgrade in the further with another stick... my budget is 150 euros over already so gotta save some money tho, should have it middle december,... btw does the bottleneck of my cpu effects my gpu and lower it performance after the upgrade or doesnt it matter that much?

Get rid of that CPU...Get an i5 4670k and you'll be rockin'! Make sure to get a Z87 motherboard like the Asrock Z87 fatal1ty killer or the MSI G65 Z87 GAMING motherboard. Get 8GB of ram. You'll be beast!

Please make sure to pick a best answer to motivate us and end the thread so you dont get confused :)

Nope it won't affect the GPU for the future, 8GB of DDR3 ram is optimal nowadays so it would be well advised to get a 2x4GB ram kit right off the bat, or just get one 4gb stick and add another identical one in later.

The 4670k and that z87 mobo is an excellent choice, pairing an aftermarket cooler with that would also allow you to overclock that CPU pretty far in the future when you're upgrading the GPU again to minimize bottlenecks.

@ badsssv1king: Once the new MB/CPU are installed, the GTX760 will run at full speed. No damage has been caused by using the GTX760 in the 'old slow' system.
Do not be worried about 'only' having 4Gb of RAM, it is quite enough for most users even today, but you should reduce startup programs to a minimum and close any running programs before starting to run a game.
You might want to get 2X2 Gb sticks then add another 2X2 Gb later rather than a single 4Gb now and another 4Gb later, current systems gain a larger benefit from running memory in dual channel mode than in the past. If you have already bought the 4Gb stick, don't worry too much, I'm just trying to squeeze the last drop of performance out of your expensive upgrade.
Adding a better CPU cooler and overclocking can be done later (if you decide to do it at all), right now the planned i5 4670K is fast enough to run a GTX760 at full speed without overclocking.
