HD4870 vs 8800GT?

My computer:
E2160 Dual Core @1.8Ghz
2GB 667Mhz RAM
ATi MSI HD4870 DDR5 512MB OC
Windows XP

My roomates computer:
E6850 Core 2 @ 3.0Ghz
2GB RAM 800GHz
Nvidea 8800GT 512MB
Windows Vista Premium

Now when playing Crysis I find that his computer generally runs at the same, or maybe even slightly higher FPS than mine. Especially noticed when settings are on HIGH with maybe 4x AA.

I dont get why this would be? My video card is one of the latest cards out with huge results in various reviews and benchmark tests smashing the 8800GT in any comparisons. It even beats the newer GTX260 in a few cases.

So anyone know why I'm not getting the FPS the card is meant to be pulling? Could it be my CPU and Ram bottlenecking?

I upgraded from a 8600GTS and feel that I'm not getting the jump up in power with the HD4870 that all the reviews are talking about.

Oh and also tested both machines in COD4 and with ALL the settings MAX we both average about 70FPS, with V.sync on. Without v.sync on I got about 70-90FPS

2 reasons. Your C2D is only at 1.8ghz, and you only have 2gb of ram. Buy an E8400 for under $200 and 2gb of ram for around $20 and you'll be set. Also, what's your mobo? Your roommates?

Sorry I'm not sure what my MB is, on the reciept it says M/B Socket 775 VGA/LAN/SOUND. BUt im guessing its a 'crappier' motherboard and if I upgraded CPU's Id say I'd need a new MB.

So you guys think the CPU is limiting the HD4870?

What sort of results might I expect if I upgrade the CPU, M/B and maybe 2 or 4GB 800Mhz RAM?

thanx for your advice

Download CPU-Z and check out the Mainboard tab.

OC your CPU to 3.0-3.2 if your Bios allows it.

It is a bottleneck at 1.8

Turning off cpu intensive options in games, like Physics, will help.

DAGGER you smashed me! Your average FPS is 52 and mine is 30!

Does you running 64bit make a huge diff?

Those results are quite dissapointing from my HD4870, so I'm hoping a better CPU will make a huge difference!

I seriously thought by just upgrading to a HD4870 I'd see better FPS than this.

Any other ideas or suggestions?

As far as I know, 64bit makes no difference at all. I use Vista x64, that's the reason for running 64bit.

Look at the 8.59 min fps. The large min-max difference with low min fps a sure sign of cpu bottlenecking. You'll need to either overclock the cpu, or upgrade to a new one.

So I know its probly a longshot, but what sort of FPS/performance do u think I would get if I went up to a E8400 or similar?

Also thanks v much for your help.

That will effectively remove cpu bottleneck, so you'll get whatever 4870 is supposed to get. :p

Well hey again, I just today upgraded to a E8500 3.16Ghz CPU and a Asus P5Q-Pro MB.

Did the Crysis benchmark again, got slightly better results but when watching the loop it seemed to be in fast forward and 'jerky'

But anyway I pulled MinFPS: 16 MaxFPS:70 and an average of 43.99FPS.

Well Im happy with it as I can now play high settings with 4x AA and average 30FPS.
