What about if I got a new motherboard that could hold everything ?

Hey guys I'm new to Tech Inferno so you can call me Shadow. Anyways, I have some questions about the Dell OptiPlex 960. I have one lying around in my house and its been becoming really slow for games. So I was wondering if I could add some new parts and revive this desktop without having to buy a new PC. These are the parts I am hoping to implement: - Komputerbay 16 GB (4x 4GB) DDR2 PC2-5300F 667MHz CL5 ECC Fully Buffered FB-DIMM (240 PIN) 16 GB w/ Heatspreaders - Intel Core BX80646I74790K i7 4790K Processor (8M Cache, up to 4.40 GHz) - EVGA Geforce GTX 970 SSC ACX 2.0+ 4GB GDD45 256Bit, DVI-I, DVI-D, HDMI, DP SLI Ready Graphics Card 04G-P4-3975-KR - TP-Link TL-WDN4800 Dual Band Wireless N900 PCI Express Adapter, 2.4 GHz 450 Mbps/5GHz - EVGA 500 W1 80+ 500W Continuous Power, 3 Year Warranty Power Supply 100-W1-0500-KR Now I want to ask a couple questions: Are all the parts which I chose compatible with this desktop PC? In the future would I be able to upgrade to DDR3 RAM, or would I have to add some other part or replace something? Do I need any additional parts to perform this upgrade? If anyone has any suggestions or advice, please tell me ! Other than that, I don't think I will need any other help! Thanks!

NOTE: I'm new to Tech Inferno so if I'm doing something wrong tell me!) Hey guys so I have an OptiPlex 960 laying around that's completely fine for normal everyday tasks but just doesn't do it anymore for gaming. So I was wondering if anyone could help me through making some upgrades to it and answering some questions about it. I'm not very experienced in changing/modifying computers & changing parts so please bear with me! These are the parts which I am planning to add: - TP-LINK TL-WDN4800 Dual Band Wireless N900 PCI Express Adapter,2.4GHz 450Mbps/5Ghz 450Mbps - EVGA 500 W1 80+, 500W Continuous Power, 3 Year Warranty Power Supply 100-W1-0500-KR - Intel Core BX80646I74790K i7-4790K Processor (8M Cache, up to 4.40 GHz) - EVGA GeForce GTX 970 Super Clocked ACX 2.0 4GB GDDR5 Graphics Card - Kingston HyperX FURY 16GB Kit (2x8GB) 1866MHz DDR3 CL10 DIMM - Black (HX318C10FBK2/16) OR (Depending on Compatibility) Komputerbay 16GB (4x 4GB) DDR2 PC2-5300F 667MHz CL5 ECC Fully Buffered FB-DIMM (240 PIN) 16 GB w/ Heatspreaders I also want to ask a couple questions which I hope someone is able to answer for me: - The desktop comes with DDR2 RAM, would I be able to put in DDR3 RAM, or would I have to get DDR2 RAM? - Would I need to get a better fan cooler for the desktop? - Do I need any additional parts for the upgrade? (If you have any other suggestions or advice please tell me) Thats all I want to know for now everyone ! Thanks for all help!
