my pc

Intel P4 processor
Hd radeon 6570
GIGABYTE 945GCM-S2L motherboard...

I am currently having problem of getting maximum performance from my graphics card but i get 40% below the card's potential... could this be because of bottleneck ? could my pc get more performance after i after i upgrade my processor?? need help

get atleast a core 2 quad

u mad bro?He's processor is really weak but the card is weak too.The Core 2 Quad is enough evene for a top-end GPU.He doesnt need nearly that much power!He needs both a new CPU and a new GPU.

I would monitor the graphics cards load with MSI Afterburner or GPU-Z after a playing a game and see if the graphics card was maxed out or not, if not then you have a CPU bottleneck (or V-sync is on). I suspect your CPU is bottlenecking the card.

Isn't it easier to monitor your CPU with task manager and see if it's maxed out?

Even if you're not bottlenecked, it's still a good idea to get a c2q or c2d, just because p4 is so bad.

It IS going to bottleneck.
I suggest taking a Core 2 Duo as it is a low end card..
You will be able to play most games at reasonable FPS but you should lower the details in newer games..

Sadly, your motherboard doesn't support Core 2 Quads.
Go for the Core 2 Duo.

Thank you. what would you recommend other than Intel i.e AMD?

Edit: Sorry this part was incorrect. Changed to prevent confusion. Everything below this stands.

The bad news is that the Core2 line is no longer made and they are still quite expensive because of the high demand for them. It is a better deal to upgrade to a new motherboard/processor/RAM than it is to get an overpriced, obsolete Core2 chip.

Personally I would save money for a new LGA 1155 setup.

You can usually get a decent core 2 duo on your local online vendor like kijiji or craigslist for cheap. I sell parts like this on there all the time. I sell C2D 6300 for $20, C2D 6400 for $25.

Dunno if you can go that route though or want to. I have had really good success with using these services though.

You can buy a core 2 quad on ebay for around $100. They overclock really well which is in your best interest. Though I'd suggest that your case have a fan on its side to blow air into the motherboard. Also with a stock heatsink you'll need to undervolt and overclock to maintain healthy temps. I'd suggest getting the 9000 series since they are the fastests while producing the least heat. Your motherboard supports an FSB up to 1600 mhz, it could go higher but you'd need to overclock the Northbridge's MCH I belive. Also, your your RAM rated at 800 mhz to achieve a 1600 mhz fsb.

The motherboard supports the entire lineup of Core2 chips including Core2Quads.

As of now I think they're at were they should be, you can get a 6000 series for about $85 on ebay. But some may not like dealing with ebay.

For a GPU i'd avoid anything below a HD x7xx card, the cards below it have a fraction of the performance of cards above them.

He has a P945 board. Although it will support any of the Core2 line it will NOT overclock very well at all. P945 was designed for Pentium 4 5xx and 6xx and Pentium D 8xx and 9xx series chips. Core2 support is with later BIOS updates and is not native.

I stand by my recommendation to do a full upgrade.

This page is very hard to read, but Core 2 Quad are not supported, the N/A under Bios means Not Support.

http://www.gigabyte.com/support-downloads/cpu-support-p...

So Core 2 Duo only! And you might have to upgrade your bios for one of those, check you current bios and tell us what it is.

You don't sound like the kind of person who whats to overclock, so stay away from E6540, E6550, E6750 and E6850.

For the others update the bios before putting in the new CPU, if you need to update the bios.

What is your current CPU?

Well, it supports a 1600 FSB so it still leaves a lot of headroom for the core 2 quads with a 1033 fsb. Updating the bios shouldn't be an issue but the alternative would be getting a new board and cpu. Though you'd have to spend more money to get equal performance to just buying a core 2 quad. I would personally just upgrade to a core 2 quad if my budget was about $100.

Good catch!

I'm blind. This is correct. I saw the whole line listed under CPU support and didn't look twice. I should not have assumed just because they were listed they are supported. Just goes to show you everyone can make mistakes!

So.....Core2Duo only. And a P945 will NOT overclock at least not much or well.

That motherboard won't be able to overclock worth mentioning. It's an old micro-ATX motherboard. They almost never OC well. Also the 945 Chipset wasn't meant for 1066 fsb really so you can't really go anywhere with it. In many cases you wouldn't even be able to overclock by 1mhz.

A full upgrade is probably in order but you could get away with getting an e6600 I think for now.

you can take a shot at buying a used core 2 duo on ebay. alternative could be a cheap but new mobo and processor. Under 100 bucks, I would look at AMD processors. Good money value

An athlon ii x2 will go along well with the gpu you have. If you plan on keeping the same motherboard upgrading to the upcoming fx 8 core processors might be will probably be worthwhile. Though you'd need to buy an appropriate motherboard. Or you could just get a core 2 duo and overclock it and wait till you can upgrade to future stuff since its just a stop gap solution. I think that would probably be the best option for its price. Also like my previous suggestion, getting a worthwhile price for the core 2 duo will depend on you buying it from ebay or some other place like it

An AMD Phenom X4 980 BE... It is great
If you are going to upgrade to newer CPUs, I recommend taking an Intel Core i3 2120.
It is good for gaming but chokes at playing BF3 online 64 player server.
This CPU beats the sh*t out of AMD FX CPUs in gaming with the exception of the FX-8150.
Also what are you planning to do on you PC??

Does it make a difference if the OP picks a CPU with a FSB of 800 or 1066, I was concerned about compatiblity with the existing memory?

FX-4170 is technically the best FX cpu and it's still a little bit worse on average than the 2120.

Piledriver should add some competitive cpu's into the market but that isn't until Q4 this year.

It shouldn't matter unless he's overclocking.

or a Core 2 Duo E6700 in your price range.

eBay is great and all. But you will get a better price using kijiji or craiglist if you can. eBay uses whole international community, and prices everywhere outside of NA are higher so local prices are always best if you live in NA.

Your motherboard will only handle up to an e6700 though. So 2.66ghz is the best you can do.
