First off I'm pretty new to all this so bear with me. So my PC is getting some what old now and I'm wondering if I could significantly affect its performance by upgrading a part or two. What made me consider this is I saw my Windows Experience Index scores and one of my scores was significantly lower than the others, my processor/ram/graphics/and gaming graphics were all 7.4-7.5 and my primary hard disk data transfer rate is 5.9. Not to leave you with this info alone I'll include my PCs parts.
