I need help to choose CPU and MB

Hi to all.I need to help me to choose best components for the price and performance.I can use my case,hdd and gpu(ati hd3650 512mb ddr3 128bit) from the old cpu.My monitor is 19' and the max resolutin is 1280-1024.I will use it for gaming but maybe on lower resolution if need to get higher fps.On medium or high settings.Now i have buy PSU seasonic SS 520GB bronze and adata 2x2GB 1333mhz.And i buy that psu cause for the upgrade that i will do in 2-3 years.Maybe i5 or i7 and some nvidia GTX6xx or amd 7xxx.And that psu will be enough for the upgrade too.Now need a motherboard and cpu.The games that i ll play are BF3,GTA4 and the new released games.I will go for intel platform.I need to have usb3.0,sata 3 and pci-e 3.0.Now i look only for asrock.I dont know how the asus or gigabyte are at the cheapest boards for the 1155 socket.Asrock b75m.Have all what i need.But maybe i can take another but some cheaper.GIGABYTE GA-H61MA-D2V.I will not make overclock.CPU,GPU will be on stock.Will be good this gigabyte mb?For this pc and for the future if i wanna to put i5 or i7+hd7xxx?The CPU will be intel pentium G840 or G630.Both have 3mb L3 cache only the Ghz is different.How fast will be the G840 in gaming?But the G630 support max 1066mhz for the ram so if i use G630 and the ram work on 1066ghz vs 1333mhz and G840 how much will be better in gaming?Now i have ati hd 3650 and with the intel pentium D945,2gb 800mhz,i get 25-30fps in gta and bf3 20-25fps low settings 800-600res.And wit the g840 or g630 and with this gpu can i play at least on medium with 25-30fps so it will be playable maybe on lower resolution?And after i get at hd7750 1gb ddr5 128bit or some like that.Will it be ballanced?Or the cpu will be slower than the gpu and work on 100%?
And another question.In the asrock site i read that for the pci-e 3.0 speed i need to have intel i5 or i7 with the gpu that have 3.0.Is this true for the cpu?

Thank you all for the help ;)

More about choose
  1. B75 and Z77 have support for USB 3.0 and SATA 3.
    They can support pentium, core i3, i5 and i7.
    Go with the Pentium G840 and you will be able to run your RAM at 1333 MHz.
    Don't worry about PCI-E 3.0 you need a really high end card to really take advantage of the available bandwidth.
    At 1280x1024 it is more on the CPU performance.
    At 1920x1080 and higher it is more on GPU performance.
  2. And what u think about the GIGABYTE GA-H61MA-D2V motherboard.Is it good chipset?If anyone have that pls tell me how is it.And if have i5 or i7 on it.
  3. You need to buy the CPU itself.
    It doesn't come with the motherboard.
    You can install up to core i7.
    Here is the CPU support list- http://www.gigabyte.com/support-downloads/cpu-support-popup.aspx?pid=4090
    That is a good motherboard.
    It is PCI-E 3.0 and USB 3.0 compatible.
    It supports second generation and third generation intel core-i series processors(2xxx,3xxx)
    The only downside of that motherboard is there is no SATA 3 6GB/s port.
    Usually SATA 2 3GB/s port is already enough for everyone
  4. I know that i need to buy the cpu and mb one by one :D they dont sell it into one package.So i think i will go for this gigabyte mb and intel G840 and after i have some more money i ll buy the new gpu GB 7750 OC 1gb ddr5 128bit or some similar and cheap like this.For my lower res is enough. : )
