GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX
To amplify what another poster wrote, Intel P35 systems use Socket 775.
Core I7 CPUs are Socket 1156 or Socket 1366. All three are LGA (Land Grid Array) designs, but they are completely physically incompatible with each other.
The best desktop CPU in existence at the moment is the (6 core) Core I7 980X. (Socket 1366.) It's also the most expensive, around $1000US. At lower prices, there are arguments about whether AMD or Intel CPUs offer the best price/performance.
