Will A Q9450 and DDR2 RAM Bottleneck A 7850?

Same for me. 5870 and severely bottlenecked in anything CPU intensive with a q6600 @ 3.5.

There were very few games I could play where I could get 100% GPU utilisation.

I agree with Marine, definitely wait till you have rebuilt the cpu/mobo/ram.

I would not recommend pairing a 7850 with a stock Q9450. My old Q6600 at 3.6GHz (which is faster than your CPU at stock clock by quite a bit) would bottleneck even my 5850...it's not "too bad" in games that would use all 4 cores of the CPU, but for any games that use less than 4 cores that are even slightly CPU intensive would see my 5850 get bottlenecked. But as others have side, it probably wouldn't be too bad if it is just single player campaigns for FPS, but for online play, that's a different story...as there are far more explosions, players and open terrain or detailed structures. As for your question would the dip down to 30s or lower be frequent on BF3 multiplayer 64 maps, yes it would be very frequent, as there will ALWAYS be lots of things going on at the same time, unlike single player campaigns where the AI opponents would only be a few of them at a place at one time nor would they spam explosives.

Your best bet for now is probaby try to find a 2nd hand 5850/6850 at around £60. Save the rest of your money and wait till you rebuild your PC before spending big amount on graphic card. Also, what PSU you got at the moment? Cause PSU that comes with a dell machine would most likely not be good enough for any graphic card that require addition 2 PCI-E 6 pin power (or even a single PCI-E 6 pin).

In my case, I have a decent Corsair 650W or similar.
 
Suppose I could always try and find a match to my 5850 and try crossfire? I had SLI many moons ago, are there still compatibility issues with running dual vid cards?
 
If you overclock it I don't think the bottleneck would be there. As you've said you can't I wouldn't bother upgrading the graphics card until you re-do your set-up.

You'd still get a boost it just won't be fully utilised. I think the bottleneck has been overstated here. It will definitely be there but even my dual core E8500 @ 4 Ghz didn't bottleneck my HD 6870 by THAT much. It was there but not as bad as is being inferred here.

The problem as said is your lack of overclocking capabilities. That's holding you back.

:-( I wont argue but not exactly taking anyones business away. Otherwise it will just be ebay or similar - rather buy from someone here I can trust or help get rid of their as they move on and upgrade but nevermind.

There's a separate subforum here at OCuk specifically for member to member sales called "Member's Market" and you need to be a member for 180days and have 1000 posts to be able to see and access it. Until then you won't see it listed at all in the forum list. See this FAQ...

http://forums.overclockers.co.uk/faq.php?faq=vb_user_maintain#faq_vb_use_cookies

No selling outside of that subforum is allowed and so it's not about "taking anyones business away" :)

NVM thanks for the post above.

Suppose it makes sense to limit fly by nights and ppl that registered yesterday. Its unfortunate however that even tho I am a fairly long standing member, but have a lost post count, I cannot access this.

...this is a Dell XPS 630i which I spent £700 on about 6 years ago. Since this is Dell, Im pretty sure with their motherboards they locked OCing which really screws me over.

To the OP...

I've just found something very interesting from some random googling. I was not aware that this was possible but it appears it is, and has been possible on various intel chips for a while. The reason it is not discussed much is because people that generally overclock would typically have a motherboard that supports manual overclocking well anyway, and so would not need to use this mod.
That being said....

It's possible to modify your q9450 so that it tricks your Dell system into seeing it as a "poor mans" qx9770. Why is this good? Because, your Dell system is more than likely locked down with minimal if any overclocking options in the BIOS. With this simple mod, your q9450 will be "hard" modified and will be seen as 1600mhz FSB (rather than 1333mhz) and 3.2ghz (rather than 2.66ghz).

Given that a lot of core2quad CPUs overclock to 3.2ghz flawlessly on stock voltage, this might be worth a shot to get you a free overclock. Not all did, but a lot would work straight off the bat on stock volts up to 3.2ghz. Hopefully it does if you try this, because I doubt again that your Dell board would support CPU VID voltage control etc.

Anyway....got to be worth a shot?

The mod is simple if you can use tape. Note the 2 pins taped up below.

If you do do this mod. Make sure the tape is secure and only covering those two pins, and not interfering with any thing else including the heatsink fan/cooling.
 
Well I thought id update you guys. Will be getting a 3770K in the few weeks as ive already got an ASUS Sabertooth Z77. If anyone is wondering, I got a 7950 instead and the CPU does bottleneck in some games
