CPU Bottleneck

I am running into CPU bottleneck issues on some of the new games I want to play (Guild Wars 2). I know my system is old, but I just don't have the money for a full rebuild. Is there any way for me to upgrade pieces? I was thinking of upgrading just the motherboard and processor and then reusing as much of my current gear as possible. I think my PSU and graphics card could handle GW2 if I got a better processor.

My hope is that I can do just a CPU upgrade now with a path to buy a new case and other components of a full upgrade later in the year.

Will that even work? Or should I just wait until I can do a full system upgrade?

Current System:

Operating System: MS Windows 7 Home Premium 64-bit SP1
CPU: Intel Core 2 Duo E7200 @ 2.53GHz Wolfdale 45nm Technology
RAM: 4.00 GB Dual-Channel DDR2 @ 398MHz (6-6-6-18)
Motherboard: Dell Inc. 0RY007 (Socket 775)    40 °C
Graphics: ATI Radeon HD 5670 (Sapphire/PCPartner)    34 °C
Hard Drives: 466GB Western Digital WDC WD5000AAKS-75A7B0 ATA Device (SATA)
Optical Drives: TSSTcorp DVD+-RW TS-H653F ATA Device
Power: Antec 450w
Audio: AMD High Definition Audio Device

Thanks for any advice.

Unless you can afford a core 2 quad,supposing ofcourse dell made a BIOS for it,then,yes get a full upgrade. Start with a better card.

Do you live near a microcenter? The one near me has been running specials like get an fx 4100 quad and board for 90 bucks. If you grabbed a deal like that, DDR 3 ram can be had for around 30 for 8 gb of ddr3 1333. If you could do those and maybe get a power supply and case you could start toward your goal but I don't know your budget. Yes you could go with a video card but I think your CPU will likely bottleneck a faster card, which is what happened to me when I picked up a gts 450 and was still running an Athlon x2.

i don't think an e7200 would bottleneck a 5670, as thats a fairly weak GPU. why dont you try a small cpu overclock and replace the GPU first.

I don't think I can upgrade my GPU with only a 450w power supply. Can I?

Yes you can, a HD 7770. But still,the CPU is noticeably lacking, and won't manage a 7850.

Thanks for the continued advice. My board has a PCIe 1.1 slot so I assumed I could not use a 2.0 or a 3.0 video card like the HD 7770 - is that correct?

Not really,PCI slots are backward compatible back to 1.1 . It'll work,just not with the same numbers a newer motherboard and CPU would give you. Hence the bottleneck.

Thanks again. Looks like all signs point to a full upgrade. If I am going to drop money on a new card, I might as well get a new MB and CPU as well.

I really appreciate all the help.

The Asus Z77 LK is just right. Plus my earlier recommendations for CPU and GFX card, but if you can manage it,a 7950 with the new BIOS is stellar. Mind, the boost BIOS isn't on all of them.
