I want to upgrade my cpu to a Intel® Core 2 Duo processor (with up to 800 MHz FSB), but i've heard of the bios reducing a fixed multiplier to a standard 6 even lower than a normal but this would still leave me at 4.8 mhz vs the 3.0mhz i have right now.. Also where can i find an Intel Core 2 Duo? I need to fix a bottleneck i've created with my gpu will this cpu fix that?

It's time to say Goodbye to your LGA 775 especially with a GTX 570 - Hell Yeah your platform itself is the bottleneck. Get an i5-2500K and ASUS P8P67 PRO (REV 3.0 or 3.1), or P8Z68-V PRO, and F3-12800CL9D-8GBXL or better F3-12800CL8D-8GBXM.

Here's something to 'Illustrate':

all those numbers are foreign to me lol, what site is cheaper tiger direct or newegg?

i'm watching part 2 of building your own computer and thats the exact mobo he uses that p8p67 pro

Q - How are those numbers "foreign to me"? It's comparing the LGA 775 Intel Core 2 Duo what you're thinking about versus the LGA 1156 i7 875K and the HUGE Bottleneck comparing GTS 450 vs GTX 480 and the ~66FPS LOSS!!!

Typically, Newegg is cheaper unless there's a sale -- in either case 'shop & compare' ;)

I meant for the part numbers lol

I can't understand what this means
Quote:
PCI Express 2.0 x16: 1 x PCIe 2.0 x16 (single at x16) 1 x PCIe 2.0 x16* [Black] (max. at x4 mode) *The PCIEX16_2 slot shares bandwidth with the PCIEX1_1 slot, PCIEX1_2 slot and USB3_34 connector. The PCIEX16_2 runs at x1 mode by default for system resource optimization.


is that one or two pcie slots?

This typically means

Single GPU:
PCIEX16_1 = x16 ; GPU <=> CPU
PCIEX16_2
PCIEX4 = x4, but variable as set in BIOS and is not part of the 16 lanes of PCIe to the GPU ; this slot can also be used for a e.g. PCI based SSD, verify compatibility, or for a PhysX GPU.

Dual GPU (SLI or CF):
PCIEX16_1 = x8 ; GPU <=> CPU
PCIEX16_2 = x8 ; GPU <=> CPU
PCIEX4 = x4, but variable as set in BIOS and is not part of the 16 lanes of PCIe to the GPU ; this slot can also be used for a e.g. PCI based SSD, verify compatability, or for a PhysX GPU.

It also means the MOBO is x16, x8/x8 GPU and seemingly a 2-WAY SLI/CF MOBO.

Unless your 'plans' include 3-WAY SLI the MOBO's with NF200 aren't needed.

Q - Are you planning on 3-WAY SLI <or> 3-WAY SLI + PhysX?
September 25, 2011 4:28:23 PM

no but i am planning on SLI eventually.

Q - How can I do SLI if there's only one x16 bus

As I stated, "It also means the MOBO is x16, x8/x8 which means the x16 lanes are SPLIT into x8/x8 so each GPU gets x8 lanes in 2-WAY. Now some LGA 1155 add a 'NF200' SLI chipset to add pseudo x16/chip but ultimately the e.g. 3-WAY x8/x8/x8 gets funneled into the x16 lanes to the GPU.

The new LGA 2011 + SB-E is 32-lanes NATIVE to the CPU so x16/x16,...., x8/x8/x8/x8 in 2~4-WAY SLI/CF.

SLI is done via a 'BIOS Key' and the type of SLI should be stated in the specifications for each MOBO -- i.e. never 'assume' SLI is supported and this must be checked. In contrast CF, Crossfire, is 'open' and the CF is limited to 4 GPU 'cores'. So is SLI limited to 4 GPU cores; example the GTX 590 per card is 2 GPU cores so GTX 590 2-WAY SLI is the limit {2*2 cores = 4 cores}.

The ASUS P8P67 PRO {P67} (REV 3.0 or 3.1) or P8Z68-V PRO {Z68} are the best (2) LGA 1155 for the money, support 2-WAY SLI/CF + PhysX, and have sufficient 12 VRM Phases to the CPU to offer low vCore.

P8Z68-V PRO - http://usa.asus.com/Motherboards/Intel_Socket_1155/P8Z6...
P8P67 PRO (3.1) - http://usa.asus.com/Motherboards/Intel_Socket_1155/P8P6...

The differences between 3.0 (NEC) and 3.1 (ASMedia) is the USB 3.0 chipset; IMO I prefer the NEC.

So if i wanted to sli m 570 would i need 32 lanes? Idk if its dual core or not I know it usues the same vapor chamber but i'm not sure on the rest..

The GTX 570 barely saturates the x8 PCIe lanes and the COST of the LGA 2011 is going to be $550+ vs the i5-2500K $220 or i7-2600K $315 PLUS the cost of the MOBO.

Here's a couple good articles:

For 'Gaming':
MOBO - ASUS P8P67 PRO or P8Z68-V PRO
RAM - DDR3-1600 2x4GB F3-12800CL9D-8GBXL or better F3-12800CL8D-8GBXM
CPU - i5-2500K ; if heavy non-gaming multitasking i7-2600K
