Hard drive prices are crazy today, and caviar blue is not the fastest WD hard drive(black is).
See if you can't manage a small SSD to start with. 60-80gb will hold the os and a nandful of games.
Buy a hard drive for overflow when prices return to normal. At that time a DW blue or green will be appropriate as overflow to a SSD.
Look first to intel or samsung for reliability.
sli applies the power of two graphics cards to improve the fps of gaming on a single monitor.
I am not familiar with games that are easily played on triple monitors, but I know there are some. If that is what you have in mind, then check the requirements for that specific game. There are some cards that will drive three monitors, but they will be most expensive. Also, I think sli can run some triple monitor games, if interested, again check out the specifics.
Most games play on a single monitor. I that case, I suggest you buy the single best graphics card that you feel comfortable paying for.
To run the 2 side monitors, use a inexpensive card like the GT210.
Here are my thoughts on
Dual graphics cards vs. a good single card.
a) How good do you really need to be?
A single GTX560 or 6870 can give you great performance at 1920 x 1200 in most games.
A single GTX560ti or 6950 will give you excellent performance at 1920 x 1200 in most games.
Even 2560 x 1600 will be good with lowered detail.
A single 7970 is about as good as it gets.
Only if you are looking at triple monitor gaming, then sli/cf will be needed.
b) The costs for a single card are lower.
You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
Even a ITX motherboard will do.
Your psu costs are less.
A GTX560ti needs a 450w psu, even a GTX580 only needs a 600w psu.
When you add another card to the mix, plan on adding 150-200w to your psu requirements.
Case cooling becomes more of an issue with dual cards.
That means a more expensive case with more and stronger fans.
You will also look at more noise.
d) dual card support is dependent on the driver. Not all games can benefit from dual cards.
e) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.
Thanks. but i am just planning to game on the middle monitor.. I will need 3 screens for work. I will be satisfied with a card which will give me great 1920x1080 gaming performance :-) Will a HD 6870 satisfy my needs? Or do i need to go HD6950? And i dont understand when u say use an inexpensive card for the other screens. Do u mean i connect the card to my motherboard without connecting the SLI bridge ?
definitely 6950 is more powerful and more value for money thing.seasonic psu is better.it's more efficient.6870 will probably max out many games but when you talk about heavyweights like BF3,Metro 2033 or Crysis,they are not enough.6950 will do fine.
