the card draws 139 watts max, i dont think 350 watts is enough headroom for the cpu and other parts of your computer with the 4670, id say get a 600 watt corsair/seasonic for the future when you upgrade your computer you can use that 600 watt psu for better parts. if you want to get a $100 card, id recommend the gtx 550ti off newegg for 99.99 after you do the $15 rebate, im a nvidia/intel fanboy but thats just me. also that card is relatively new (1 year old)
