HD4870 bottleneck problem

Hi guys,

first of all happy new year 2009 to you all :) 

Here's the specifications of my pc I'm currently using.. some components are way older but had to keep them you know...

CPU - Pentium 4 3.0Ghz Cedar Mill
VGA - Sapphire HD 4870 512Mb
Ram - Kingston 1Gb DDR2 667Mhz x 2
Mobo - Intel DG965WH
PSU - Zalman ZM750-HP 750w

I had to play games at 1024*768 resolution because of the 15" monitor I'm having. Currently playing prince of persia 2008,farcry 2 and nfs undercover. I noticed even that at this resolution when I set the graphics settings to max, some places in the game it runs well but sometimes it gives me performance issues.

now this is weird, I also tested the prince of persia 2008 and nfs undercover with max settings at 1440*900 but had the same issues with the performance. I mean I feel that the game performance is same at both resolutions.

I suspect that this is a bottleneck for the GPU so I've searched a bit on the net regarding this problem and there some people says that to avoid a bottleneck you must have atleast q6600 (stock clock is ok) or C2D higher processors. I don't know about my mobo and ram but hope they are ok for this GPU..

what do you guys think about this issue ? this mobo DG965WH has no OC facilities and the best processor it can handle is the q6600 ( fits to my budget also ). I'll think of buying the q6600 but please I need to make sure whether I'll be able to play games at 1024*768 and 1440*900 with max settings after buying q6600.

I found this thread also
http://www.tomshardware.com/forum/255837-33-hd4870-512m... and the output from the unigine is shown below.



Please let me know your opinions about this issue. thanks and sorry for the long description..

CPU - Pentium 4 3.0Ghz Cedar Mill = your problem.

Single Core CPU even though it has HT, its def the bottleneck...

Also running Vista with only 2gb of RAM is a problem

OK, I need to type faster:(

I would go with the E6700 also.

But I suggest you to just save up for a new mobo, CPU and RAM all at a time.

I think you should get a E8400 core 2 duo it is awesome value for money.

And another thing you have your AA set at 16x in that screen shot, that is usually very tough on a graphics card set it down to 4x and see if it helps XD

mehcrim, I provided a link to all compatible Core 2 CPUs for that motherboard (http://processormatch.intel.com/Co [...] me=DG965WH ), but unfortunately the E8400 isn't on that list. He'd have to buy a new motherboard along with an E8400 (which is what I'd do).

The guy just doesn't pay attention to other posts, Ghislaing :) .

PS: Mehcrim, Anisotropy isn't Anti Aliasing.. 16x is fine for Anisotropy.

thanks for the replies guys :)  anyway would you think that I can get away with good performance in games if I use q6600 and also avoid bottlenecking the HD4870 .because this board doesn't support e8400 the best option for me is q6600 ( I couldn't buy both the mobo and cpu so I'm hoping to get a q6600 for now and later I'll OC it with a new motherboard ) .

ausch30, I'll try going back to windows xp sp2 and see if that helps also . I thought may be the dx10 can help a bit on the gaming so that's why I'm still using vista :) ..

Nah, 2gb + vista = a big problem.

Vista uses 1GB itself, which means you'll have 1GB of RAM left for other tasks.

Q6600 pretty much sucks for gaming. E8400 is THE gaming processor.

Once again, I suggest you the save up for a mobo + new processor + new RAM all at one time, just to get the best out of it, instead of buying weaker components all apart.

DX10 makes your system work harder and will amplify any weaknesses.
