I wanted to build a computer for the first time. considering that i dont know much about what i was doing, i posted a thread here asking for a build. I took those builds into consideration and decided to put some of them together with others and my own and came up with this. My question is will all this work and how well will it work? Should i change anything? what should i change?
Don't use a RAIDMAX PSU. They are among the least reliable. Get a Corsair, Antec, XFX, Rosewill, or Seasonic model instead. XFX and Seasonic are probably the best, but are both usually more expensive.
I don't recommend new Samsung HDDs. They are just re-branded Seagate HDDS and Seagate's reliability is also questionable. I recommend Western Digital a lot more. The Caviar Blue drives are a good choice, the Caviar Blacks are a more expensive, but higher performance model, the Caviar Greens are a slow and low power modee (do not use them in a RAID nor NAS system), and the Caviar Reds are best for NAS systems.
The Radeon 6870 is a good card, but it's a little overpriced these days. A highly factory overclocked Radeon 7770 would offer similar performance at a lower price and a Radeon 7850 could be had for a little more money and has far higher performance.
It's actually fairly simple. There are really three settings to consider for basic overclocking with the AM3/AM3+ socket CPUs. CPU voltage, CPU multiplier, and the BLCK frequency. You want to get your CPU frequency to around 3.8GHz or 4GHz. You can increase the CPU multiplier and/or the BLCK frequency to do that. The voltage might need to be increased to get to a certain frequency and how much it needs to increased, if it needs to be increased, depends on the individual CPU.
There are many online guides to do this (even those catered to the individual CPU model and platform) properly.
Before you even decide if you want to overclock, I'd recommend waiting until you've built your computer and checked to see if it performs well in games that you play. If overclocking isn't necessary, then there's no god reason to get into it. It increases power consumption (frequency hikes don't increase it by much, but increasing the voltage can increase power consumption significantly) and if done improperly, there is a risk (not much of one, but its there) of causing damage to the CPU, motherboard, and memory. However, there are many fail-safes implemented these days, so damage is extremely unlikely.
There are more things that can be done such as overclocking the system memory, the graphics card's GPU(s) and memory, and even the CPU's L3 cache (can't do that on Intel CPUs, but you can on AMD CPUs) for more CPU performance and more, but these are usually the most significant.
HDMI versus DVI... Well, they use the same digital signalling, so it doesn't really matter unless your display has built-in speakers. HDMI has audio lines whereas DVI does not. In fact, because they use the same signaling, they don't need active converters to use an HDMI port or a DVI of a computer port for a display that uses the other port. There are even cables that have both HDMI and DVI connectors.
Wow I got stumped reading that but I got the gist of what you were saying. Is that why people have very large Psu's? I'll try the build out with the games I play. and I guess i'm going with an hdmi cable. I had no clue they were so similar.
Large PSUs are generally for power-eating graphics cards. CPUs, even overclocked (within reason), tend to not suck as much power as some very high end graphics cards do. They most certainly can't best multiple graphics cards that all suck a lot of power each.
