  3. Dual GPU micro-stuttering is far worse with low end cards than high end cards. Might be better to just replace the 550 TI with a faster card like a Radeon 6870 or GTX 560 TI.
  4. And keep the quality HX520watt PSU!
  5. Glad We could help. If you ever have any more questions or need of assistance, Just make a post and we'll be there to help!
