How much improvement will I see?

So currently this is what I am running.

Mobo: Asus P5B Deluxe Wifi
Processor: Intel Core 2 Duo E6400
Power Supply: Antec 550w
Memory: Corsair 1gb ddr2 800
Video Card: Nvidia 9800gt

My questions are yes, I know with all the quad cores out and even the i7s possibly becoming mainstream, with the parts I have below on hand (left over from Christmas) how much improvement if any should I see and or which parts should I keep or not worry about putting into my current system.

Mobo: Gigabyte GA-EP45-UD3P
Processor: Intel Core 2 Duo E7200
Power Supply: Corsair 750w
Memory: GSkill 4gb ddr2 800
Video Card: Ati 4850

Thanks for any of your help and suggestions.

  1. Jus adding those extra RAM and the gfx card itself u will see a very notable difference....So goin wit the other components u sholud be able to see nice difference...
  2. I don't think you will see any notable difference with at processor. If I'm not mistaken, doesn't it have less onboard cache but is simply 45mn with slighly higher clock?

    As gkay09 said, go with the RAM and graphics card. You'll be happy with those without wasting money.
  3. I think that the PSU doesn't need to be 750W...600W or 650W would be fine.
  4. If you overclock the e7200 to 3.6ghz+ and try to OC the 4850 (though they can't OC much), you'll see a big difference with AA/AF cranked.

    Is it worth the jump...not really IMO if you payed retail newegg prices.

    If you sold your old PC and got in on 30% eBay cashback on Black Friday, then yeah, it's an almost free upgrade.
  5. on asus board pci-e slot is only at 1.0 and gigabyte is pci-e 2.0 how big of a difference does that make?
  6. I agree with gkay, the RAM is gonna give the most noticeable boost in performance and would probably be the best bang for buck option.

    With 800 speed RAM and the 4850 i think you should be ok with a 600 - 650 PSU but with faster RAM i would probably go for the Corsair PSU just to cover your back.

    I think you should see a big difference in AA/AF without an overclock. I thought that AA was all GPU intensive and had little to do with the CPU?
  7. I agree with Noya - not enough of a performance improvement to justify the upgrade cost.
    The HD4850 and 9800GT are nearly equal in performance. PCIe v1 vs PCIe v2 isnt a factor in a single card system.

    Overclock your E6400 to ~2.8Ghz on that Asus P5B Deluxe, add the 4GB of DDR2 800 RAM (or even 2GB of RAM if you're still on XP).
    Look into overclocking the 9800GT.
  8. WR2 seems to have the best answer, actually. If you overclock the CPU, all you really need to buy is a good CPU cooler which can also cool the other components as well (b/c of fan and the cooler's design)-that way you can OC the 9800 GT a bit more if it gets hot. The 9800 GT is OCable, so just do that. Also, you don't need to buy a new PSU this way, either. The best way to save money and upgrade your computer!
