Will my CPU Bottelneck or block some performance for my card..

i couldn't follow that link regarding your pc, but your cpu generaly doesn't affect the gpu (unless your cpu is really old and slow.)
regardless, if you dont have a 2.0 port, you wont be able to plug it in to your mobo.

yes there will be a bottleneck. you can generally overclock q6600's to 3ghz+ very easily. If you can get it to at least 3ghz you should be fine.

It's extremely unlikely he can OC the processor as it is an HP which is a shame. At default that processor is going to bottleneck the GTX 470 and especially so in games that only use 2 cores(there's still a lot of them being released.)
What is the native resolution of your monitor? Have you switched out the power supply in that system? If not you are going to need to do so to use any decent video card.

I was wondering if the Q6600 will indeed bottleneck a GTX 470.

At what resolution do you play? Low resolutions are more CPU dependent.

You may have a bottleneck, but that could easily be lessened by OC'ing your cpu... The 6600 was on of the best OC'ers of the C2Q series.  

PCIe graphic ports are all the same size and my PCIe 2.0 cards have been plugged into a PCIe 1.0a port and they worked so what are you on about?

^ +1 to that. pcie2.1 is backward compatable with 1.x, however some older motherboards dont have a new enough BIOS to support 2.1 cards.

I play on 1650 x 1050 . Say what mobo should I get if I were to overclock?

if your going to replace the motherboard you may aswell just get a whole new setup. Spending money on a new motherboard just to overclock your current cpu is a huge waste. If you want a new motherboard best off switching platform and going for a phenom x4 or core i3/i5 setup.

yeah but all that stuff would cost like 500 bucks. I currently only have 360 bucks. Im trying to post my q6600 but ******* craiglist isnt posting it, god they require so much i dunn how they are even up.. what would you perfer... the 360 of course is from the return of the graphics card.

It would be more of a waste to buy a Phenom II x4. They are basically equivalent to his current processor if he could overclock it. A $50-60 motherboard to OC would be a lot cheaper than a $50-60 motherboard and a $120+ processor.


Ebaying the Q6600 should fetch you $100 or so. That plus the $360 is $460. This means you can do a full upgrade to the new Sandy Bridge Intel chips;
Intel Core i5-2400 - $190

ASRock H61M-VS Motherboard - $60

G.SKILL 2 x 2GB DDR3 1333 - $40

Sapphire HD5850 Xtreme 1GB and Total War: Shogun 2 - $150

That totals $440. The video card isn't quite as fast as the GTX 470 but not by a large amount. It is 15% or so slower. It also overclocks very well which should at least make up the difference but whether you do so or not it should be excellent for 1680x1050. The i5-2400 trounces the q6600;

Of course you haven't responded my earlier question about your power supply. If you are still using the one that came with the system that will need to be replaced which means more money. Something like this would be a good choice;

If all of this is too much then yeah, I guess replace the motherboard and get a good cooler to overclock the Q6600 instead.
GIGABYTE GA-G31M-ES2L Motherboard - $53

ARCTIC COOLING Freezer 7 Pro - $30

With the video card I linked above that's $233 or $283 with the PSU.

Well, I will be working here soon out of town for a construction company. I will safe until the ivy boards come out then maybe consider buying them. I dont game so hard atm so I'll just wait for the next generation of upgrades come out.

Well, you could forget about overclocking and just get the HD5850 instead(and the PSU if you need it.) The Q6600 at stock is still alright and pretty good in games that can take advantage of more than 2 cores. A more reasonably priced/powered card like the HD5850 would be a better choice especially if you really paid $360 for the GTX 470.
