RAM: 4GB DDR2-SDRAM
Current GPU: NVIDIA GeForce 8400 GS (Microsoft Corporation - WDDM v1.1)
Current BUS Interface: PCI-E 1.1x16
Not sure about my power supply at this point but will check tonight when i open my cabby but im positive its over 300 or at least 400 watts .

Video Card I want:

The card should run perfectly fine. What do you plan to do with the card?

It will be compatible, your 8400gs is in a PCIe slot which all mordern cards uses, i would recomend you something better, GPUs with 2gb of vram doesnt help that much than a better/faster card at the same price.

Let me explain like this:

HD6670 2gb GDDR3 http://www.newegg.com/Product/Product.aspx?Item=N82E168... cost $85

VS

HD6670 1GB GDDR5 http://www.newegg.com/Product/Product.aspx?Item=N82E168... $89

For 4 dolars more you will get a MORE powerfull card, which is way better for gaming. Card with 2GB of Vram are usless when comes with low end GPUs, it start matters when the card have enough power to use the 2GB of ram and lower end cards like that will NOT use the ram, so is useless and you will be paying for something you wont use at 100%


Hope that you didnt buy it already and change your mind, you will get a much better performance for you money with a 1gb GDDR5 card than any DDR3 card with 2 or more GB...

Cheers!

Thank you so much, but someone also told me that because the 6670 is a PCI-E 2.1 bus slot and my motherboard only holds PCI-E 1.1x16 it might not work and told me to learn towards a 7750. What are your views on this ?

It's all about "bandwidth capabilities" .

PCIe 1.0 x16 its pretty much like an PCIe 2.0 x8 (half speed) BUT it SOME cases, i ran a PCIe 2.1 card (my HD6790) on a PCIe 1.0 x16 and I could game pretty good, and when i upgrade for a PCIe 2.0 i see no difference in bandwidth or kind off...

PCIe 2.0 can transfer more bandwidth than PCIe 1.0, but it will only used by really powerful card, those are higher than HD6870 or GTX560..

In theory the PCIe 2.0 is not yet capped at its limits and the PCIe 3.0 is pretty much an marketing "new" technology which moster cards like the GTX680 or HD7970 use to get better performance, but the diference with that and the PCIe 2.0 its minimum...

Also all cards that are PCI-express bus are backwards compatible, i mean a card with a 3.0 PCIe bus will work in a PCIe 1.0 slot with a litte bandwidth cut but the difference again is hard to see in real world gaming..

If you can, get the 7750, is now when your processor will bottleneck it, i would say that getting it will let you a nice upgrade path of processor/move, then reuse it, and you wont need more untill you start playing very intensive games at really high quality and resolution...

Also for PSU, you should think about getting a cheap but GOOD PSU in some time short... It will be like the guaranty of your PC...

Thaaanks for your help, i guess ill go out and get the 7750 then and yea im planning to upgrade my processor soon. Any recommendations in my situation with a 7750? What motherboard would you suggest as well?

Since the 7750 is a PCI-E 3.0, i hope it works well with my 1.1 .

It will work, for sure...

I would recomend you a nice and cheap intel combo, an I3 2120 + H61 mobo for around $200, a good 400W certified 80plus PSU around $50 and you are golden for light gaming for some time, and that processor + mobo will not be outdated in some time soon, being able to move with no bottlenecks even a big guy like GTX560ti or HD6870...
