Will intel dh55tc support core i5-3450/i5 2400 and gtx 560/hd 6870??
No, the motherboard has an LGA1156 socket. The processors you listed need an LGA1155 socket.
LGA1156 is the first generation of Core processors.
LGA1155 is the second and third generation of Core processors.
Ok,thanks...then which mobo should I buy??
Please keep the price cheap!!
I would stick with ASUS, Gigabyte, and MSI names for quality. Since you are wanting to save money, the B75 or H77 chipsets are probably what you would be interested in.
Newegg search for LGA1155 motherboards
The motherboard you currently have is a Micro-ATX motherboard. If you don't have room in the case for a standard ATX motherboard, you will need a Micro-ATX for a replacement.
Another thing to consider is your OS, if you are currently using an OEM license, that license is bound to the motherboard you will be removing. If this is the case, another OS license will be needed when purchasing a new motherboard.
Sorry,it all went above my head!!!
How about this:
Gigabyte GA-H61M-D2H Motherboard ??
The Gigabyte GA-H61M-D2H will work
