Some good articles for determining whether or not the various DDR3 "levels" are worth it. My personal take was that the DDR3-1333 (w/ 7-7-7-20 timings) tends to be the best value overall, as real-world gains are almost negligible beyond that.
I'm currently at work and haven't had time to read through this, but from what I've gathered, PC3-10666, PC3-10660, and PC3-10600 are all identical; it's just a case of manufacturers rounding differently. (The actual max bandwidth being 10666 MHz.)Last edit: 2010-07-22 03:36:40 |

Regarding memory speed, I know that the i5 750 maxes out at 1333,
but I intend to overclock to about 3 to 3.3 GHz, something safe.
For this overclock, I read that I would need to push my memory to about 1600.
Any ideas?

No, the i5 750 maxes out at 1333 due to the lack of a 2:12 multiplier.
You don't need to push your memory to 1600. You can choose a lower multiplier than the default 2:10 that your i5 750 set. |

I understand that choosing a lower multiplier like 6 or 8 would work, but if I leave the multiplier at 10, and set the BCLK at about 160, then I could get a CPU at about 3.2 GHZ and Memory at 1600.
would that be better?
I've never overclocked before, so any advice on reaching a conservative stable, optimized overclock would help.
Also, would leaving the memory at a lower clock like 1333 instead of 1600 impact performance to a degree where you would notice it?
Thanks FragKrag |

No, it won't impact your performance really. I had my memory at 1280MHz for the longest time and even though I'm using 1600MHz right now I can't feel any difference.
That would work though, if your RAM is ok with 1600MHz |

Also, does the RAM timing make any difference?
say between a 1333 Mhz c7 or a 1600 Mhz c9?
And any good recommendations on a budget monitor 23-24 inches for about 200 USD or less?
preferably 16:10 =)
You've been very helpful!!!
Thanks! |

The 5850 is stronger but the 460 is cheaper decisions decisions.
If you sli i'd go 460 because then if you find you're not getting enough 460 in sli is a good set up.
Else i'd just go 5850. also apparently until ati brings up their drivers a 460 is better then a 5850 in sc2 lolLast edit: 2010-07-23 12:38:31 |

| Eh, i'd go 460 but it depends on the rig, if i'm running like a i5-760 i'd do it easy because then when i need to get more power for w.e reason i just pop in another 460, but if we're keeping it to 1 card only 5850 is a significant enough jump up in power to consider Even against a 460 that is oced.

what's the limit for when having pci-e lanes at 8x will hamper SLI/crossfire? I know I read that 2 5770's won't be affected, but 2 5850's probably will be. Would two 460's be? Most of the time people do all of their testing with their OC'd i7-965/975's so it's
I'd have to buy a new PSU to run in SLI anyways, so that's out of the picture
I'm actually slightly concerned that a 5850 won't fit in my case, or rather it would just leave like 1/2" of room to work with lol having a shorter GTX 460 is nice for sure |

Oh, the x8/x8 bandwidth limit shows up at the HD 5870 (definitely), but it doesn't cut off a very large amount of FPS (maybe 3-6) back when they actually compared it. You could try overclocking your PCIe lanes a bit as well around 10MHz or something (not sure how stable it will be though).
I wouldn't worry about it though. As long as you can get an SLI bridge you probably won't hit much of a barrier. |

Hey guys, so I'm about to buy a laptop, and I just wanna quickly get your opinion before I make a final decision.
I'm currently consider the following three:
$599.99: http://laptops.toshiba.com/laptops/satellite/L640/L645D-S4037
$719.00: http://www.toshibadirect.com/td/b2c/cdetland.to?poid=483708
$759.00: http://www.toshibadirect.com/td/b2c/cdetland.to?poid=484036
For the customizable ones, they would have i3 processors, 4 GB of RAM, and 320 GB HDDs.
For the one where I have an option of Intel HD vs NVIDIA GeForce 310M, I think I'd go with the Intel HD (it's $100 cheaper).
Right now, I'm actually leaning heavily toward the L645. I found it on Amazon for 599.99, free shipping because I have Amazon Prime, and I think I can get $50 off of that cost with this promotion they're currently having for Prime.
It's processor is a 1.8 GHz AMD Phenom II, triple-core, so that's better than the i3-350M, which is dual-core, right? The i3 is a 2.26 GHz processor, but the AMD is better right?
And the graphics card on the L645 is the ATI Radeon HD 4250. I don't know GPUs that well, though. Is this one good? How does it compare to the Intel HD and the NVIDIA GeForce 310M? |

Reading through this post for 10 mins, I've really learned a lot about building computers more than I've ever had in searching for sections in Google for 1-2 hours. Really appreciate the info man.  |

Hey Frag, I read your guide and I give it my seal of approval. Not that it means anything.
Got me a GTX460 and I got to use it for a few SC2 games. That thing's great =)
The best upgrade I ever got for my PC though is definitely my X25-M 80gb SSD... Wish it was bigger but yeah SSDs are like that!Last edit: 2010-07-23 15:25:21 |

Actually, the Phenom II Triple Core will probably be weaker than the Intel i3 at SC2! SC2 currently does not utilize extra cores very well, and the higher clock speed + inherent architecture advantage that the i3 holds will pull it through.
The 4250 trades blows with the new IGP that is onboard with the i3, and the GeForce 310M should be better than both of them. The HD 4250 will probably out perform the i3 integrated if drivers come into play, but the Nvidia 310M will win out over both of them.Last edit: 2010-07-23 16:23:06 |
