CPU bottleneck?

Hi all. I dont think this will be an issue but wanted some feedback. I have an E6600 (OC to 3.0) on a 680i mobo with 4gb ram and I am running a 8800gtx (630mhz core). I was thinking of upgrading the vid to a gtx260. Think (in general, I know some games/apps are more cpu intense than other) I would be hobbling the gtx260 with the E6600? Mostly play games like supcom, tf2, bioshock...

Good upgrade. You'd get about 80% of what the GTX 260 can output. Of course, you could get the rest if upgrade to i5 and OC to 3.8 GHz or 4. GHz. But as for gameplay, there's little difference between that and what you plan to do - e6600 and GTX 260.

Thanks for the quick reply HundredIslandsBoy. Sadly I am on a LGA775 (680i) so the max CPU upgrade for me without having to replace the mobo and memory would be a Kentsfield or Wolfdale (currently running conroe). Maybe upgrade to a E8400 or Q6600 and OC a little? Thinking the E8400 would be better for gaming??

At any rate, the biggest question I was hoping to get answered was that I would realize a significant and justifiable performance gain for ~200 bucks. It sounds like I should see significant improvement but I will not be unleashing the gtx 260 completely.

A descent upgrade I hope.

Thanks!

80 % of a gtx 260 is way much better than a 100% 8800 GTX :)

Hmmm, the 275 does have 2x the memory... but it's almost $100 more than the 260. Perhaps I should look at some benchmarks between the 260 and 275. Nice suggestion Milos, just not sure if I want to go more than $200 for the upgrade. Plan to build a complete new system in 12 - 18 months... just wanted something to bridge me between now and then :)  Some of the newer titles are a little sluggish at 1900 x 1200 with AA turned on. Also, I was able to get my E6600 to 3.2 on air but she started getting hot under load so I backed it down to 3.0. I am a little timid about going above 3.0. At any rate, I will consider your suggestion. THanks!

Milos-stancene, sorry, I must have my profile settings incorrect. I'm looking at US Dollars (I'm way over here is Seattle, WA). http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Since I am too much of a wuss to OC my CPU any further, I am thinking two things..
1) I can only get about 80% performance out of the gtx 260 due to the E6600
2) I would get < 80% performance out of the gtx 275 given my current cpu.

It just seems I would be wasting $ and performance unless I can crank more out of the E6600 or upgrade the cpu to a wolfie or quad.

I think your suggestion would be the best recommendation if I had better cooling and a bigger sack. :)  3.2ghz was pushing 66-68 dec C. Right now under load @ 3.0 she floats 60 - 62. I am afraid 3.4 would go over 70 which scares me :) 

Thanks again!

Thanks ZipZoom, I guess I have been a nVidia fanboy for so long, I forgot that Radeon is actually back in the fight these days. The price certainly makes it attractive. I'll need to check out some performance charts !

Cheers,

Or you could get the e8400 first, OC it to 3.6 Ghz (9 X 400 bus) and squeeze even more our of your 8800GTX, Depending on the resolution, you may not need a GTX 260 or HD 4890. What size monitor do you use?

Dual monitor. Main is an Apple Cinema 23" , the second is a 19" so I am capped at 1900x1200 and 1600x1200 respectively. I run at max res whenever possible on the main.

I guess I am drifting off the original subject... but at the end of the day, I am just looking for the best bang for the buck upgrade :)  Current build...

CPU: E6600 @ 3.0
VID: 8800GTX
RAM: 4GB corsair dominator (TWIN2X2048-6400C3DF)
mobo: Asus striker extreme (680i sli) (although I have no idea how I could fit two monsters in the box, the 8800 takes up almost two slots itself)
HDD: 2x WD 150gb raptors
Sound: xfi fatality
OS: vista 64 bit (although I have a copy of win 7 ultimate 64-bit I have been too lazy to install).
Power: Thermaltake W0106RU 700W

Thanks!

You're system is still pretty good, more than adequate for gaming. Unless you just want to burn some major cash by going with new mobo, new CPU, RAM, go with your original idea of upgrading one component that will carry you over for another year... so, it's either CPU or GPU. If I was in on your shoes, I'd upgrade to an e8400 and then to a faster GPU, either HD 4890, GTX 275, or HD 5850 whichever fits the budget.

Thanks again for the feedback. Sounds like the two focal areas will be the CPU and GPU. As you suggested, I will probably start with the CPU and see if that brings a couple more FPS to the 8800gtx, then, if needed, up the gpu to a more current model as suggested above.

Cheers!

You'll have to crank up the e8400 to at least 3.6 GHz (9 x 400 bus) to max out all what that 8800GTX can give. Anything past that, there might be some stability issues or heat issues and besides, past 3.6 Ghz the gains won't be noticeable, at least not when I do it to my e8400 anyway. What is your CPU cooler?

Will do the job ! Get the 260, overclock your cpu over 3.2 ghz and get ready to do some headshots :)

would he need to do a bios upgrade because the e8400 is 45nm(?) I believe?

Good question. I recall flashing the bios once when I got the board which corrected memory frequency display issues, that was back in 02/07 ish time frame.

According to asus I need "Core 2 Duo E8400 (3.00GHz,1333FSB,L2:6MB,rev.C0) ALL 1502"... eg bios rev 1502. I am pretty sure that I am running version 0701 so I would need to flash the bios again to recognize the new cpu.

Thanks for the reminder!!!!
