The bios version is ESTK20A
And model is MAHBOY NO DPK. I've ran cpu-z .
I don't really know about graphics cards but i just need one equivament to the gtx 870m
What i have is an intel pentium(r) 2cpus
2gb ram and an intel hd graphics card
And i want a core i5 or i7, at least 16gb ram
And a nvidia gt 860m graphics card
Can i upgrade my pentium g645 to core i7 to my desktop ? and i also want to add a gtx 870m gpu and add more ram about 30gb.. Will it be possible to do thet in my desktop
