How much is my CPU bottle necking my video card?
So I got an HD 4890 for my computer and I'm wondering how much the rest of my system is bottle necking the video card. There's no doubt the video card is bottle necked and I'm planning on upgrading anyways.
CPU: Pentium D 820 dual core (2.8GHz)
Motherboard: Asus P5LP-LE (One PCI-E x16 not PCI-E 2.0)
Memory: 1GB DDR2 (Everest claims it to be running at 200MHz)
Well if you need any more info let me know. I just want to know an approximation of how much GPU performance I am losing because of the rest of my system. Thanks.

Your graphics card is operating at about 26% load max with that setup. Main issues are that the CPU has a memory access bottleneck and can not feed your graphics card fast enough. Also your memory might be a very cheap variant and it definitely needs more to buffer data from the hard drive. The motherboard does not allow maximum bandwidth due to having only a PCI-Express 1.0 slot.
likely definite. there's a basic thank you to locate if a CPU is bottlenecking your photographs card. Take a interest which you know your photographs card ought to be enjoying on max settings. something like modern conflict 2. Now examine the FPS difference between max settings and lowest settings. ideally, the backside settings FPS ought to be very almost double the max settings FPS. The nearer the two figures are, the extra you CPU is bottlenecking your video card.
Your Radeon 4890 card is running at less than half the speed it would, on a more current CPU (like a Core 2 Duo or Core 2 Quad, at 2.8 GHz per core or higher), because of the CPU bottleneck.
