Ok, so, with no refferring to my issue, i want to say that this forum solved me a lot of problems so thx for your great database of users :#.
And here we get started. Since 2 days ago, when i bought my brand new nVidia GTX 750 OC 1Gb GDDR5 i'm dealing with this issue : I run a game like Battlefield 3 or Far Cry 3... anything that's made with new-gen graphics and i get lower fps than i get with my old Radeon 3400 GPU - very old
So i've googled a bit and made some threads and i found this unusual word : Bottleneck ( and in my mind it was like... a bottle in my neck/does graphic cards uses bottles or have necks X.X whatever )
And, after i found some infos about bottlenecking, i realized ( even now when i write a word it's lagging :| ) so i realized that compatibility of my CPU with my GPU was the last thing i could think about to change my old GPU...
Anyway, what i'm trying to do is ( also i want to know i'f my CPU bottlenecks ) :
1. Does my CPU bottleneck ? ( using an decent Intel Pentium Dual Core 5200 @ 2.5 GHz
2. If it does, can i stop this bottleneck somehow ( i'm feeling like i'm using an old 2000's windows 98 computer - getting lagging when writing a thread with no other apps opened :/ )
3. Is my GPU or CPU bottlenecking ?
4. Is there anything in the specs below that can cause bottlenecking ?
CPU : Intel Pentium Dual Core 5200 @ 2.5 GHz
GPU : Asus nVidia GTX 750 OC 1GB GDDR5
Motherboard : Foxconn G31MX
RAM : 4 Gigs DDR3
PSU : 450 Watts

Thx for reading and maybe share your ideea to help me :)

Well the best processors in that bunch are the Q9400 and up. Here are a few options, but just shop around for what you are willing to pay (especially shipping)

Overclocking these chips and the older Q6600 is quite easy. Even with the stock fan 3.0Ghz is possible. A cheap cooler like a Hyper TX3 can probably get you to 3.4-3.6Ghz easily.

I would say you have a pretty big bottleneck caused by your CPU. Your GTX750 is probably demanding a lot more information then your 3400 did. The CPU might be overheating trying to cope, or it just doesn't have the bandwidth to satisfy the GPU.

If you have the motherboard model, might be fairly easy to find a used CPU that would be a significant upgrade. For a few hundred it would be possible to replace the CPU/Motherboard/RAM.

As you are the only one who replied to my thread, please, can you tell me a cheap and also decent CPU that won't bottleneck with my GPU and also that will be fully compatible with my motherboard ? ( i found this : http://www.cpu-upgrade.com/mb-Foxconn/G31MX.html but there are so many processors and i really dont know which one is the good one or if there is a good one ) :/
