Computer not as fast as I would think

So I'm running a Dell XPS 400. Specs from the system window read as:

Intel Pentium D CPU 2.80 GHz
Memory 3582 MB
System Type 32-bit OS (Windows Vista)
ATI Radeon HD 3600
C: 104GB of 144GB
D: 50GB of 71GB

Now after a little research on MOBO and CPU's, after this bright idea my crappy dell MOBO is what is slowing me down, I needed more specific info so I came across CPU-Z or CPUID. Now it holds alot of info most of which could be made up for all I know. Here is snipets of the report hopefully including the important specs.

CPU:
Number of cores 2 (max 2)
Number of threads 2 (max 2)
Name Intel Pentium D 820
Package (platform ID) Socket 775 LGA (0x4)
Core Stepping B0
Technology 90 nm
Core Speed 2793.2 MHz
Multiplier x FSB 14.0 x 199.5 MHz
Rated Bus speed 798.1 MHz
Stock frequency 2800 MHz
Instructions sets MMX, SSE, SSE2, SSE3, EM64T

Chipset:
Northbridge Intel i945P rev. 00
Southbridge Intel 82801GB (ICH7/R) rev. A1
Graphic Interface PCI-Express
PCI-E Link Width x16
PCI-E Max Link Width x16
Memory Type DDR2
Memory Size 4096 MBytes
Channels Dual
Memory Frequency 332.5 MHz (3:5)

MOBO:
Mainboard Model 0FJ030
Made by Dell


Ok so now to the why I think its slow and how I judge it. My old lady has a computer that is fairly similar except its custom built. She has a 3 core AMD CPU, 4GB DDR2 Ram, same OS. We both play rift she plays at medium high settings with little to no lag. I play at the lowest possible settings in game and through my GPU control center. It never runs smooth, if I'm alone in a field with not so much as a tree around I lag.

Should I buy a new mobo that supports all current hardware. For now im looking for a cheap short term fix. something under 200-150. eventually I plan to build from scratch starting with CPU+MOBO hopefully utilizing some of my current hardware until i can afford new. Which leads me to another question can a DDR3 MOBO support DDR2? Thats enough for now thanks for any and all help

  1. Hello, and welcome to THG.

    Seems like you need a whole new computer. I would say get a better processor. Pentium D? I know P4's are still around, but from what you have just explained, it seems a better computer would suit you.
  2. I agree with dogman get a new computer...Build one yourself they are way better plus no junkware from dell/hp/gateway, just stuff that you'll never use and only slows down your machine. But if your not in the market for a new PC I would upgrade you video card, you can get a radeon HD 4850 on ebay for about 50 bucks, installation is a sinch and it should improve your gaming experience. I know the HD 4850 is two year old tech but it will still crush the low end new stuff at the same price range.
  3. Get a GTX 460 768mb card
    this is best deal
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814121390

    these are your specs
    http://support.dell.com/support/edocs/systems/xps400/sm/specs.htm#wp1053343

    the dell 375w can handle the gtx460
    You need to check to see if it has the PCI_E 6pin connector
    it comes with a 4 pin molex power adapter if you dont have the plug on PSU

    it is $125 after rebate on USA Newegg

    Great thing is you can use it in new build
    Still a very powerful and up to date card
    also look for a SLI motherboard in your planned future build
    and you can run two of these together
  4. or you can go with the hd 5850 extreme,they are at only 139 at newegg.

  5. A pentium d is about 5 years old . I'd be surprised if it has half the real computing power of a triple core AMD cpu

    Not worth upgrading . Too old
  6. Nice choice but requires 500watts which is a little too much for the Dell
    375w continous (@450 max) Power Supply

    The GTX 460 spec sheet
    http://www.nvidia.com/object/product-geforce-gtx-460-us.html
    shows it needs only 450w which that number is usually inflated by video card makers

    One thing I noticed about the GTX 460 is it needs two 6pin connectors
    so you would have to make sure you have the right adapters

    he is looking for a quick upgrade now until
    he does new build
    as he stated in his original post

    so if he gets a 768mb GTX 460 now which will
    definilely improve his games

    he can then use the card in his planned future build

    please read the posts completely and try to
    help the poster instead of pushing
    your personal opinions
  9. i think it would have some bottle neck issues.But he could transfer his gtx 460 to his newer pc later on.
  10. The only thing I am worrying about is the need
    for two 6 pin connectors

    I am not sure if his power supply has any
    If he doesnt

    He would need two 4 pin molex power connectors
    and two 4 pin to 6 pin adapters

    the XPS might only have one molex
    I am not sure
    So he would also have to get a 4 pin molex splitter

    If he only has one molex then that means that
    he would have both 6 pins on one 12v rail

    He would probably be alright but
    I would fell better if he had two molex off of different
    rails for connecting

    The great thing is on his new build he
    could get a sli board
    and pick up a second card

    Dual Asus OC'd GTX 460 768mb DirectCU cooling
    is a very respectable setup

    I dont think you would get anywhere near the full potential of a GTX 460 , and since thats already replaced by the GTX560 its probably a fairly limited future path to buy in to

    IMO if all you want is a quick cheap gfx card then get a 9800GT or Ati 4850 off Ebay .

    Anything else is just not worth it IMO
  12. looking for something to carry to future build
    that would work in current system

    He could always SLI with another GTX 460 in future build

    Dual GTX460 will match up or beat a GTX560
  13. Outlander if you can suggest a card that would work in current system
    and be good for future build
    then please do
  14. A 5770 is a good low power option for just over $100 or even a 5670 would give you a good improvement. You could consider an Athlon II X3 and an AM2+ board so you can keep you RAM. This board is only $45 http://www.newegg.com/Product/Product.aspx?Item=N82E16813157204 and an Athlon X3 is around $80 add these to a 5770 and you have a good gaming PC
  15. A 5770 is a good option also

    as far as cpu/mobo (which the X3 Rana would be good choice as simon12 pointed out)

    But remember the OP has a Dell system so really hard to swap in
    a standard form factor mobo

    he would need to also get a case and PSU for new build
    which he is planning in the future
  16. looking at this
    http://www.tomshardware.com/forum/293177-33-hd5770
    the GTX 460 outperforms the HD5770 according to general consesus

    the HD 5830 would be the direct competitor to the GTX 460

    I think if the OP would want to run dual cards later
    the GTX 460 because the Nvidia drivers are more stable than ATI
    (alot of complaints about CF with ATI drivers)
    would be a better choice

    as a single card option than the HD5830 would be worth
    looking at
  17. hola desde mexico ,
