5770 40fps cpu bottle neck?

Hey guys,

I decided to do one last upgrade on my old and dying gaming rig. It's got a DualCore Intel Pentium D 820, 2800 MHz (14 x 200) and 3072 MB (DDR2-533 DDR2 SDRAM). I basicaly repeated the test found Here. While they got 60 FPS @ 1920X1200 on ultra high I got <benchmark>
<average min_fps="19.959843" av_fps="24.692440" min_fps_ms="50.100594" av_fps_ms="40.498226" />.

So is it my lack of DD3 and quad core holding me back 40 frames? Or am I missing something?

Thanks,
Levi

the pentium d is old and i believe its bottlenecking your gpu pretty much, if you have money you really should upgrade your cpu.

Its not really about the Quad or DDR3, your CPU Is holding you back full stop.

I didnt think a cpu could hold you back 40 frames. Do I need a new platform? I don't think their are that many better upgrade cpu's for this old socket.

A Pentium D is LGA775 actually the same socket as all the core 2 duos and quads. A lot of the older motherboards still can't use them but it is theoretically possible that yours can. Tell us the brand and model of your motherboard. If you don't know it you can use CPU-Z to find out;

I have a faster set of g-skill laying around. I should probably put that in. Yeah I have been telling my self since last year I was going to upgrade but with the new usb and sata standard I kept putting it off, then yesterday for valentines day my girlfriend was like you haven't bought anything for your computer in a long time, so I decided I would do one more upgrade to this old computer before getting a new one. So my girlfriend totally bought me a 5770 =)

It's a dell xps 400 is that helps, what I looked up I should be able to use a Intel® Core™2 Duo Processor as long as it's a lga 775.

Can any one confirm this?

This is the cheapest quad core I can find. Do you think this is compatible with my system and will help me gain the 40 frames I'm missing? Could I coast another 2 years on this system until I completely buy a new one?

Thanks for every ones help. I'm in a hurry to figure this out in case I need to return the 5770.

i think you get more help if you start a new topic in the new system build section, good luck :)

How much do you have to spend? You can build a pretty decent gaming system for under $500.

Since you already have the memory, hdd etc, and graphics you can actually finish up your rig for $250 or less...
