Advice - New Mobo or update processor

First of all I want to thank everyone in advance for taking the time to read this.

I bought a HD5770 a while ago only to see how my cpu was bottlenecking it badly (I have a Intel Core 2 Duo E4300 @ 1.80 Ghz Conroe). Now I'm planning an update, but I'm not sure if it's worth changing the mobo or just the processor.

My motherboard is an Asus Striker Xtreme and I was told that, with the latest bios, I can put some nice processor on it. But I have no idea about processors, so, after seeing the list of suported processors on asus.com I can't figure out if the processor allowed by the mobo are worth not changing the mobo it self.

My goal is to have a mobo and processor that don't do any bottleneck with the video card. If I can achieve that changing only the processor (and adding some more ram, I have 2GB now) without expending much that would be great.

My other option was changing mobo, processor and ram (i'm thinkign about PhenomII X4 955BE, Asus M4A89GDT PRO/USB3, Coolermaster V8 and 2x2GB DDR3 1600 Patriot sector 5). I know changing it all will bring greater performance, but, is it worth the money? It's around 550 euros just those 3 things.

Ah, just to notice, I use the PC mostly for gaming :)  I'm not planning on OC, so maybe I can save some on the cooler?

Thanks a lot again.

You could upgrade to an E8400 or E8500 for under $200 http://www.newegg.com/Product/ProductList.aspx?Submit=E... Do not know about prices in Europe though. Both would be a good match for the HD5770. Unfortunately the only quads you board supports is Q or QX6xxx series. You might be able to pick one of those up cheap used.

i'd get a e8400 if you plan to upgrade again when the sandy beach, or bull dozer is released. If not i'd go ahead and shell out the bucks for a new i7 mobo, i 5 if you want to have dual channel instead of 3 chanel ram

price

e8400= 150

price to upgrade $600-800
i7-930 cpu
S300

i7 mobo
$200-250

6gb ddr3 1600Mhz
$180-250

When the new stuff comes out in 2011 or 2012 it will be alot better than what we have to day, higher FSB, and better clock speeds so if it was me i'd just get an e8400 and wait it out. Or even a q9650 ($300).

Heres some benchmarks

When it really comes down too it most games today are GPU based not CPU.

Thanks a lot for your answers. I had a look at prices and I can get this:

-INTEL CORE2 DUO E8400 3.0 GHZ SK775 1333 MHZ 6MB DUAL CORE
-4 GB ( 2X2 GB) DDR3 1333 CORSAIR CL9 DHX

for 350 euros, saving 200 euros.

There are just a few things that worries me:

-with the new processor I can upgrade the Ram from the old 800Mhz I had to the 1333, true?
-Will my power supply be enough? I have a Nox Urano 600W.

Thanks again

As long as the motherboard supports RAM @ 1600Mhz, otherwise i believe it's throttled back to the Memory Standard (mine was 667Mhz on my last setup) of the mobo. BUT you cannot use DDR3 with an E8400 unless the motherboard supports that, i haven't seen very many motherboards that use DDR3 with a LGA775 processor though, so be sure to double check that.

Also, your power supply should be able to handle it, just make sure there's enough amperage on the 12v rail(s) to support your GPU.

This is what is stated at the mobo site at asus:

Front Side Bus: 1333/1066/800/533 MHz *1333 available when CPU's supporting 1333MHz FSB)

For what I've seen the E8400 have a 1333MHz FSB, hasn't it? So it would work at 1333MHz, right?

Also, please, could you tell me how can I check if the power supply has enough amperage on the 12v rail? For what I have seen on the Nox site, It have this:

Output power:

+3.3V: 24A
+5V: 32A
+12V1: 21A
+12V2: 22A
-12: 0.6A
+5VSB: 2.0A

If I have only one gpu, then I'm using only one 12v rail, so it has 43A? I am mostly guessing here :)  Would that be enought as long as I have only one gpu?

Thanks a lot for the answers.

Look through the manual that came with the mobo, in the ram section, it should say what frequencies it can handle (667,800,1066, etc.) this is not the FSB. Also, this would be the section to check if it can handle DDR3 or not.

And as for the PSU, I can't state if the quality is good cause I've never heard of that company, but yes, It has 43Amps total (12v1+12v2) and should be able to handle any single GPU card up to a GTX480, and even some crossfire setups (like 2 5770's :o  )

Honestly, if you're gonna stay with a core 2 duo, then I suggest you stick with DDR2 so that it will save you hassle by for sure being compatible with your mobo, but if you are set on DDR3 the just be sure that the mobo supports DDR3.

EDIT: Is this you're mobo?

If so, i'm afraid it can't go beyond DDR2 800. :(

Thanks a lot fot the quick answer.

Yes, that's my mobo, so I will use DDR 800 instead. Thanks a lot :)
