This depends on what you're going to do.
If you're doing heavy multitasking or other tasks such as 3D rendering or video encoding, you will benefit more from the four cores.
If you're doing casual computer use and computer gaming, you will benefit from the two cores with the faster clock speed.
- Dual Graphics card, or single powerful one? I'm bouncing between a single 1 GB Raedon or dual nVidia 9600 GT ("SUPERCLOCKED"), which leads up to the same amount of VRAM, or a dual 8800 GT 'SLI enabled'. And can someone tell me the advantages/disadvantages?
There isn't really any single video card right now that is better than two pre-gen cards in SLI/Crossfire. I'd go with the 8800 GT SLI. It actually performs better than some 9600 cards in some cases.
- 4 GB, or 2 GB "Low Latency" RAM?
Not sure what latency you get with "low latency" but I'd still personally go with the 4 GB.
- What is a RAID harddrive?
Firstly, RAID stands for "Redundant Array of Independent Disks". Think of it as SLI but for hard drives. In other words, it's using multiple hard drives (ideally of indentical brands and capacities) to increase performance and/or reliability.
There are numerous ways that you can have RAID configured, but the most typical ones are RAID 0 and RAID 1.
RAID 0:
When you write a file, it gets split apart and written on all the hard drives at the same time. This effectively doubles (or triples, or quadruples, depending on how many drives are in the array) the write speed. It also works for reading files. When you read a file, it will read all the pieces of the file from each hard drive at the same time, reaping the same performance benefit.
Pros:
-Dramatically increased performance in both reading and writing.
-Since files are being "spread apart" on all the hard drives, your total capacity will be the sum of all the hard drives put together (For example, if you have 3 100gb hard drives in RAID 0, your total capacity will be 300gb)
Cons:
-If you lose the data on one hard drive (due to hard drive failure or anything else), then ALL the data on every hard drive is lost. Because each hard drive contains fragments of each individual file, if one were to be lost, the data pieces on the rest of the hard drives become useless garbage. If you use RAID 0, make doubly sure that you have a reliable data backup.
RAID 1
This is the same as RAID 0 except for one thing: Instead of writing pieces of the file across multiple hard drives, the file in entirety is written to every hard drive. Because the entire file is being written to each hard drive, the writing performance won't be any different than that of a single drive. However, the reading performance increase will be there.
Pros:
-More reliable storage of data. If one of the hard drives were to fail, you still have the full data on the other drive(s), meaning no data is lost.
-Dramatically increased performance in reading files
Cons:
-Because every hard drive is a "mirror" of the other hard drives, your total capacity will only be equal to the lowest capacity drive in the array (but usually they all have the same capacity). In other words, if you have 3 100gb hard drives in RAID 1, your capacity will still be 100gb
-No performance increase in writing files
- Please and thx lol
yes this is a prebuilt Iol, I have my reasons - I'd build one, but again, I have my reasons. So please, don't bother.
And those people who are telling you to overclock the quad core processor yourself are not quite giving good advice. Because it is a pre-built computer, you have no guarantee that this will even be feasible. It completely depends on the manufacturer and your motherboard/case. Many pre-built computers are made without any consideration of if you'll be putting extra cooling equipment inside it (there might not be room). Also, the fact that you're buying a pre-built computer insinuates that you might not be comfortable doing this in the first place. Buying a pre-built computer and then overclocking it doesn't make a lot of sense in my opinion.
