Hi,
I've decided to go with i7-4765T (quad-core, 35W) CPU for my TVS-671-PT-4G, got it from ebay for $250.
Got 16GB memory as well: G.SKILL Ripjaws 2x8G DDR3L 1600 (PC3L 12800) F3-1600C9D-16GRSL
Upgrade was easy, even since this is first QNAP unit I open (I have multiple Synology boxes but recently switched to QNAP, got TS-870 Pro filled with 500GB 840 Pro SSDs and 10GB Ethernet), took about 30 minutes with no rush. After upgrade powered on the unit, it started, then rebooted itself and then booted just fine, CPU and 16GB memory recognized, no worries.
Happy with power consumption, new CPU is more powerful than Pentium but consumes less power:
QNAP TVS-671 4x HGST He8, Pentium G3250 - 59.6W idle, 68W file operations, 32.8W sleep
QNAP TVS-671 4x HGST He8, i7-4765T - 52.3W idle, 58.4W file operations
Now awaiting for Intel X540-T2 10GB NIC to complete my setup
P.S. This upgrade will definitely void the warranty as they put a red substance on almost every screw you have to remove...like 30 of them
