Antec Three Hundred Illusion Black Steel ATX Mid Tower Computer Case - Retail

Seagate Barracuda 7200.12 ST3500418AS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

SAPPHIRE 100283L Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail


How does this look for a gaming system? Keep in mind that I am planning to crossfire it with another HD 5770 in the not too distant future.

How much of a performance increase would I expect a Phenom II X4 955 to have over a Phenom II X3 720? Would it better for me to get an Phenom X3 and spend my money on something else like a better graphics card?

Is there anything else that I could save money on?

  1. ^ You can cut short on some components without any significant performance hit...
    1. PSU - You wont need a 750W PSU for HD 5770 crossfire...Instead check out the Corsair 650HX, even better 650TX (You can easily manage the unused cables inside the case and anyways it doesnt have a side window so it the extra wires wont matter much...

    2. Mobo - You can still overclock the 955 with the 790X/ 790GX mobo to 3.8-4GHz level...What matters the most is the CPU cooling...

    3. With the money saved on the PSU and mobo, you can get the HD 5850...it would better suit your requirements...
    And changing the CPU to X3 720 wont affect the gaming performance...and that too when overclocked...

    So the above suggestions would save you some money without any hit in performance...
  2. 1. 770T-UD3P Gigabyte for mobo
    2. P2X3 720BE or P2X4 925 if insist on quad
    3. Corsair VX550 for non CF/SLI gaming rig good to go
    all savings to channel into
    4. HD 5850

    Cheers ^^
  3. doesn't the 5770 perform worse than the 4890 in games?

    i would go for the 5850, and you shouldn't need to crossfire for a while.
  4. Might want to actually make your links work...

    You can find better RAM for less. For example: G.Skill Ripjaws.
  5. Sorry about the links. They are now fixed

    How good is the 770T-UD3P Gigabyte mobo for overclocking the CPU?
  6. If I went even further down the scale and bought a Phenom II X2 550 BE would I notice much of a difference for gaming? Is there still a chance of unlocking the cores on the Ph2 X2 550 and Ph2 X3 720 or have AMD stopped it?
  7. The 550 and 720 are still unlockable but its always a gamble. If you get the cores unlocked they are not as stable as a 955 or 965. If you want a quad core its suggested you get a 955 or 965.

    720 is really good for gaming if you are considering saving some money. If you can dish out the extra money the 955 is the way to go.
  8. 770T-UD3P: OC + Unlocking thread :P

    One has to get the right stepping of 550BE for best chance of success though

    If your doing any overclocking, ignore the 965. Its the same chip as the 955, just you pay an extra $20 for a factory overclock. So if you're doing it yourself, there's absolutely no reason to pay for a head start...
  10. The only thing about the 5850's is that they're hard to come by right now. The 5770, however, seems to be plentiful. As for performance, it's only slightly slower than the 4890, thanks to the former's 128-bit interface.
