New 5870 + E6600 = bottleneck? What should I do?

I'm running:

Intel C2D e6600 OC'd to 3.2ghz
Nvidia 680i MB
4GB DDR2 800mhz
ATI XFX HD 5870 (newest addition to the rig!)
Soundblaster XtremeGamer
Hauppauge WintTV Tuner
2 WD 640gb 7200 HDs
1 Samsung 1TB 7200 HD
620watt PSU

What is my bottleneck? What should I upgrade? I'm just seeing slow performance in GTA4 and a few other titles.

Help me out ... what ought I to do?

Thanks!

I would sell your E6600 and pick up a used Q6600 for ~$100-110. I would say get the 45nm 775 quads but Nvidia is greedy and only supports those on the 7 series.

You could always trying to do a complete wipe of your hd also. Did you make sure you erased your previous drivers?

Thanks cory1234

I should note:

If it is, indeed, a CPU bottleneck, I am looking to upgrade in the range of $300 for new MB, CPU, and RAM. Other suggestions, folks?

Hmmm... do you know how much of a performance increase I'd be getting from the E to the Q?

I don't think I want to wipe the HD... DO have backups, but that's excessive at this point for me. I've used Drive Sweeper to remove the nvidia stuff -- video drivers and physx

If you get a G0 Q6600 for a good deal, it will be the quickest and easiest upgrade, and you WILL see increases across the board, most notably in the newest games, as well as HD playback and encoding. I got one for really cheap, OC'd it to 3.4, and it absolutely smokes my old E6600.

Not solely nVidia's fault. Intel is partly to blame. nVidia tested the 680i with preproduction Yorkfield samples. They worked. Shortly after,when nVidia refused to share SLI technology with Intel, Intel retaliated by making the production Yorkfields incompatible, even with a BIOS update.

You'll want a quad core to go with a 5870, no doubt about it. Dual cores are going to be a god-awful bottleneck.

I'd go with AMD for this one due to price. You could either go the route mentioned above, which would get you DDR3 ... go the ultra-cheap route and get a low-end AM2+ board, which would let you keep your existing RAM. Something like this

and this

would come in at like $140 and still be a pretty awesome machine. I mean, some day you might want to upgrade past that, but it'll be fine for now.

You'll need $400 to go the i5 upgrade path. $200 CPU, $100 mobo, $100 DDR3 RAM. If you're using a 24" or 28" monitor, it's worth the upgrade. What resolution are your games on?

If you have one of the "newer" 680i mobos, it should accept 45nm CPUs. And your mobo easily runs to a 1600 fsb.

An easy cheap upgrade is to sell your E6600 (avg about $65 on eB*y), then throw in a $100 for an E8400 that you can to 3.6 Ghz 1600Mhz FSB. That should give about 20%-25% performance from your 5870, be able to push it 20% harder than than what your E6600 is doing now.

For a "free" upgrade, with your 3 hard drives, if you tried RAID 0, that could also give you slightly faster load times and slightly faster frame rates too if you do FRAPS or Flight Sims or games that record video.

These are just two options of many: Go with an E8400 for $100 (selling the E6600) or $400 for an i5 platform.

if i remember correctly AM3 processors work on AM2+ motherboards so you can keep your ddr2 ram.

you could go for the X4 955 but you would have to find a AM2+ motherboard that supports 125w tdp cpus.

for the $200 guy, just get this processor.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and this motherboard. use your old ddr2 ram.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

for the $300 guy, you could go for this x4 955 + asus M4A79XTD motherboard combo.

http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...

and this corsair ddr3 2x2gb ram.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

just $1 over budget.

Hey, people. Please do not resurrect an 8 month old thread. Among other things, so much has changed that any recommendations you make to the original poster are no longer valid.
