I guess depending on how hard core you want to get with it. If your pared with a really good video card, it should hold up pretty well. Price and performance should be well up close to modern PCs.
The only thing I would worry about is the rest of the PC, the CPU requires a chipset to run, as that is a older chipset, you might not be able to get fast bus speeds and maybe even no USB 3.0, or SATA III and might be limited to SATA II. That is the only thing I could think of.
I had a CORE2QUAD @ 3ghz (q9650) for the longest time, even when I had the ITCH to swap it out, the benchmarks for a i5, or even a mid i7 (quad core CPUS) where really not much fully better. I was looking at spending $1200 for a minor improvement. When i finally did it, I made sure I got a system I could grow with...M2 slots, USB 3.1 and 3.0, plenty of PCIe slots, over clocking, etc. Sure the CPU is faster but, the bus speed is almost double the old one, the memory is 10X faster, even the SATA ports are v3 (6gb/s) as the old one was SATA 2 (3gb/s).
It made a difference, that is the ONLY real bottle neck I could think of going to a little older Xeon CPU. Otherwise, I would be tempted to do the same thing by the numers, it looks like it could keep up with alot of CPUS of today.
