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?
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 to upgrade $600-800
6gb ddr3 1600Mhz
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).
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.
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 )
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.
