for gaming? as the years progress you may need to lower quality settings to keep good framerates but if this is not an issue then you can probably manage it.
just make sure you check everything twice before you buy.
#ram sticks to #channels. ie 2 or 4 sticks for dual channel. 3 or 6 for triple.
cpu socket to mobo socket
power calculation to psu wattage
psu connectors required. some mobos and vid cards have multiples
For BF3 and Crysis2 you will want all of the video card you can manage to buy. An AMD 7770 really is going to get you to low graphic settings for either of those games. MW3 will most likely be ok since it is still a DX9 game. To be honest I have always tried to get everyone up to a GTX660 or 7870 through any means necessary. The i3 is a good choice for a budget build. The 500W is overkill for a 7770, but if you want a better card you will want it. A GTX660 or 7870 would run fine on it.
Also, I would replace the B75 board with an H77 board. It has more features that you may potentially use. The B75 is more targeted towards a business or office PC. The ASRock H77M is a good price on Newegg right now.
The PC will be fine as an Office and application machine for quite some time, but as a gamer it will most likely need an upgrade sometime along the way to 5 years. As far as functionally work, it should work for many many years.
Do i need 500W for my shappire HD 7770 OC Ghz edition, or... -
Corsair 430W ? - whats the difference...?!
And should i get a fan for my pc ? - like cooler master sickleflow red 120 ?
And about HD 7870 - i would buy that card, but it cost a little to much...
I would think about buying that card, but i dont know how much my pc will take elecricity pear month (
- You do not need a 500W PSU for a system with a 7770. A Corsair 430W would work just fine. Heck an Antec Earthwatt 380W would work just fine. The 7770 at load barely uses enough to even vouch for using a 6 pin PCI-E connector. The 7750 is the next card down and it doesn't need one. However, 500W will give you room for a better card later, but as I suggested I would do what you can to do that now.
- Most cases come with at least an exhaust fan. In reality that is the only fan you need on a modest system. As long as you are exhausting the warm air out of the top rear of the case, it will draw air in from the other vents due to negative air pressure. Once you get into heavy overclocking and higher end components that turn your PC into a space heater, they you will need more airflow.
- Most cards today take roughly the same about of power at idle or in 2D modes, basically when you are on your desktop. They all down clock themselves and go into power saving modes so really your desktop activities won't use any more power on a higher end card. When you jump into a game or another 3D app, the card will clock up to it's intended speeds and the higher end cards will use more juice. The GTX660 uses about 75W more power than a 7770, which isn't all that much.
Also, here is a review you can thumb through that shows why I'd suggest spending the money on a 660, or 7870. It doesn't show the 7870 in the review, but just assume its right next to the 660 in performance. You can see the gab between the 7770 and 660 is quite large and for $100, I'd suggest it highly.

Ok, so i am buying Radeon HD 7850
So, do i need a Power supplie - Corsair 430W or Corsair 500W?
And should i get a fan too?
But if i will not buy a fan, my pc will survive normal for 6 years?
The 430w would be enough, but it teeters on the edge of it. I would go with the 500w to be perfectly honest. It also allows you a little upgrade room.
You don't need any additional fans as long as your case has an exhaust fan. Your PC should last 6 years easy. The item that usually fails first is your hard drive. The other components should last until the PC just doesn't give you enough performance to support the latest software. I just upgraded a buddies Core2 e6300 with 4GB RAM and installed Windows 7 on it. It runs just fine and that thing is 7 years old.
