Yet another gaming PC

APPROXIMATE PURCHASE DATE: Within the next 4 weeks BUDGET RANGE: Preferably around $600 for what I need, but I'll pay more for better performance

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, Minimal video editing/encoding, Web browsing

PARTS NOT REQUIRED: Keyboard, Mouse, Monitor, Case, HDD, CPU, OS


PARTS PREFERENCES: I'd prefer to stick with ATi for the video card

OVERCLOCKING: Probably sometime in the future SLI OR CROSSFIRE: Maybe in the future, I'd prefer to stick with a single card for now.


ADDITIONAL COMMENTS: As I said above, I have the CPU, case, and hard drive already. Here's what I've been looking at for the entire setup:

CPU: Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor - Retail (Have already)
PSU: CORSAIR CMPSU-550VX 550W ATX12V V2.2 SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Retail
GPU: XFX HD-577A-ZNFC Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
Motherboard: ASUS P7P55D PRO LGA 1156 Intel P55 ATX Intel Motherboard - Retail
RAM: G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL7D-4GBRH - Retail
Hard Drive: Western Digital Caviar Black WD6401AALS 640GB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive (Have already)
Case: COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case - Retail (Have already)

Some stuff is found in the replies, but I'm basically wondering if the 550W PSU would be enough to power two 5770s in the future. Any other suggestions are welcomed as well :D

  1. That Corsair PSU has 41 amps on the 12V rail. Thats as good as some 750W PSUs. It should power a system with a single 5850 easily.
  2. Awesome, that's exactly what I wanted to hear! Now it just needs to come in stock sometime when I'm home...

    If you want the option of Crossfire/SLI in the future, you should buy the necessary parts now to save you the trouble of having to upgrade a few things later on. You'd want a mobo that will run both cards at x8/x8 and also a PSU with 4 PCI-E connectors since each 5850 requires 2.

    ASUS P7P55D PRO LGA 1156

    Antec TruePower New TP-750 750W Continuous Power (only comes to $95 after rebates)

    Also, faster RAM (but with slightly higher timings) for the same price
  4. Good point about the connector's, didn't even think to check that. That is a decent price increase for having the option to crossfire in the future, so that puts me on the fence a little bit. I've read that crossfire's gains mostly occur in higher resolutions. Obviously you can't tell the future, but would you anticipate needing to add a 2nd 5850 for performance increases at 1680x1050 in the future, or would the gains be pretty minimal? Adding a 2nd 5850 certainly would simplify my upgrade path, but if the performance gains are pretty minimal I might opt to upgrade to a better single card in the future (although that might need extra power from the PSU...)

    Apologies if I seem to be rambling, I'm just trying to figure out what the best upgrade path would be (adding a 2nd card vs replacing single card)
  5. At 1680x1050 single monitor you wont need a second 5850. If you get into multiple monitors or a larger monitor you might end up wanting the second card.
  6. I'll probably stick with the 550W PSU then, if I can find it. I don't anticipate upgrading my monitor anytime soon, and would probably build a new computer before then. I'll probably switch to the RAM build recommended, since it's only $5 more.

    Anyone else have thoughts on the build, or should I start buying the parts that are in-stock?
  7. Since you've scrapped the idea of Crossfire/SLI, the motherboard you listed on your first post (Asus P55 LE) will be fine.

    As for everything else, I don't see any problems :)
  8. Awesome, thanks for your help :D
  9. Ok, due to the shortage of 5850s, I'm thinking of going with a 5770 instead. However, I'm not sure that I'll be completely satisfied with its performance, and would like to re-open the possibility of crossfire. Would the 550W powersupply listed above be enough to crossfire 2 5770s? I'll probably switch to the motherboard build recommended above (

    Editted the OP to reflect these changes.
  10. No, you would need something in the 600+ range for crossfire 5770s
    Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2 / EPS12V version 2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC
  11. Looks good, but how about I'm not too informed when it comes to power supplies, what's the difference between 80 PLUS certified and 80 PLUS bronze certified?

    I ask because there's a nice combo with the 5770 that I could take advantage of.
  12. That PSU is actually slightly better than the EA according to JG. I just recommended the less expensive EA because it fulfilled your requirements and was cheaper (before combos).
  13. Ok, cool, that's exactly what I like to hear :D I did my own research on the certification thing, so that's understood as well. Thanks for your help, I should be able to order soon!
  14. The TP 750W is a bit excessive, go with the one jbaker suggested :)
  15. build said:
    The TP 750W is a bit excessive, go with the one jbaker suggested :)

    Is there any downside to it being excessive? The combo deal makes it cheaper than the one jbaker suggested, so I'm very tempted to go with it.

    Combo is here btw:
  16. You should have mentioned the combo earlier then :non:. If it's cheaper then go for it.
  17. "I ask because there's a nice combo with the 5770 that I could take advantage of." :P Shoulda linked to it though, you're right.
