    Hi guys, I'm currently running an AMD Phenom 955 BE and a GTX 295. I was wondering if my ASUS M3N-H HDMI motherboard will be bottlenecking this setup at all?

    Cheers

    What frequency is your cpu and ram running at? I doubt motherboards can bottleneck an entire system just by themselves.

    My processor is still running at 3.2 ghz (stock). I haven't overclocked it yet. However, I think if there will be a bottleneck, it'll be with my RAM as this appears to be running at only 400mhz.

    Usually the only way a motherboard would bottleneck a system is if
    1.) It has a 4 pin CPU connector and you need 8
    2.) You need more PCIe Lanes than it gives
    3.) There are insufficient I/O connections on the backplate and inside
    4.) The FSB is limiting your CPU overclock
    5.) Your Northbridge has limited features
    to name a few, there are others but I doubt that the motherboard is bottlenecking your system

    I expect I'll be upgrading the motherboard soon anyway. I was looking at the MSI NF750-G55. This board will give me an AM3 socket and will support quad sli should I want to add another gtx 295 at some stage.

    Problems with Quad sli are : large power draw, large heat production, poor support in games ( most of the time 3 way sli beats out quad ), the dreaded microstuttering. Back to the topic, your cpu should be fine with the 295 but I would definitely sort your ram out as 400MHz is just too slow. As i'm guessing this is a ddr2 board, you'll need either a PC6400 or PC8500 kit.

    Would this OCZ Reaper RAM be compatible with my ASUS M3N-H HDMI DDR2 board?

    400MHz... DDR2...

    So, could that actually be 800MHz?

    OP, can you get us some screenshots of CPU-Z? They'd help us a bit, with regards to the RAM issue.

    Did they even make 400MHz DDR2?

    Yeah, your RAM's running at 800MHz. Long story short, DDR2 has 2 pulses per clock cycle - one going up, one going down.

    Its actual speed is 400MHz, but its effective speed is 800MHz (because it does 2 things per clock).

    Ah i see. Well in that case I may aswell wait until I get a DDR3 board before I upgrade my ram.

    Cheers

    Are you just planning on sticking to 1 graphics card? If so, the MSI 770-C45 board is about £60 and wins awards left, right, and centre. Couple that with 2 sticks of DDR3, and you could do the whole upgrade for about £100, subject to price fluctuations.

    I'm just gonna be using a single GTX 295 for now, but i really wanted a board that could support DDR3 and have 2 pci-e lanes so i could quad SLI a pair of 295's later down the road if I wanted to.
