My specs:
CPU:Intel core 2 quad q8400
GPU:Ati Radeon HD 6850 1 GB
My friends specs:
CPU:Amd Phenom II 945
GPU:Nvidia 250 GTS 1 GB

Your current PC should be comparable to your friend's. What is your budget for the new PC?

My butget is 450 $ for video card,processor and a new power supply.

Depending on clock speeds your CPUs are very similar in terms of performance. Your 6850 however is more like a GTX460 so its quite a bit faster then his GTS250. I'm not sure I would buy a S775 machine however. I'd look to nothing less then S1156. Even getting S1155 with a lower end CPU like the 2100 might be a better idea.

Pretty much this.

The PhII 945 is probably 10% faster than your q8400, but the HD6850 is likely 2X the GTS250 (that's a new 'recycled' G92 core).

Keep your video card and move to a new mobo/cpu. If you are in the US a PhII 955BE is $105, a nice AM3+ motherboard around $100 (nice Crossfire/SLI boards: $140), and $30 for 2x2GB DDR3.

With $200 or so left over you have quite a number of options in addition to your PSU ... a Cooler Master HSF comes to mind.

That does not compute. You should be doing a bit better, not worse.

Your cpu is about the same capability.
Q8400 passmark=3685
Phenom ii 945 passmark=3626.
Is either cpu overclocked?

The graphics cards are comparable, with the 6850 considered to be a few tiers higher than the GTS250.

How much ram is on each system? 2gb could be part of the problem, 4gb is better.

What is your psu? Why do you think you might need another?

To help clarify your options, run these two tests:

a) Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.

I don't think he has his system yet. I think in the OP he said he was going to buy. He just wants to make sure his is better then his friends.

You are right, the post IS a bit confusing on second reading.

But "My butget is 450 $ for video card,processor and a new power supply."

would indicate that he already has some parts, particularly a motherboard.

Not flaming, or starting am AMD/Intel thread war here, but THIS is what drives AMD crazy.

No How || No Way is a Q8400 a better CPU that a PhenomII 945. It just ain't happening. Sorry.

At stock, and over-clocking, the PhII 945 wins hands down. Passmark is useless. End of story.

True enough, but for gaming, the graphics card is usually the prime factor, and in this case, the 6850 should be better than a GTS250.

That's why I don't care about those "bungholio" marks. I actually ignore/passover all synthetic benchies when I read about a new device. The 2900XT was supposed to be faster then the 8800GTX. It could barely keep up with the 8800GT. EXCEPT in 3DMark. If I want to know which CPU is better, I'll look at the tasks that I actually do. Not just some theoretical task that no one ever does.

I just decided to buy a Ati HD 6850,Asus M5A78L-M LX MoBo,AMD Phenom II X4 955 Black Edition,A 650 w PSU,And 4 Gb of ram.
So do you think my PC will be good enough to play Call of Duty MW2 and other good games at max graphics?

Not sure about max, but you should be able to make everything pretty enough.
September 18, 2011 2:44:44 PM

Make sure that it is a quality psu from a reputable brand.

Be sure to verify that your RAMs are on the Asus memory QVL list.

They also qualify memory for both AM3 and AM3+ CPUs (should both be in the same zip file). If the RAMs you select are on both lists you should have an easy future upgrade path.

Be sure to check the far-right column on the lists describing the DIMM slots - not sure if it will be an issue for you but I would suggest going with a single 4GB stick since there are only 2 slots on that mobo.

And though it might be pushing your budget, the Giga-Byte GA-970A-UD3 AM3+ is $98 and quite an upgrade over the board you selected.

Fer sure.

I normally guesstimate 2/3's GPU to 1/3 CPU but, as in all else, it's a bit more subjective than that.
