I am planning to buy G.Skill RipjawsX DDR3 8 GB (2 x 4 GB) (F3-12800CL9D-8GBXL) and Sapphire AMD/ATI Radeon R9 270X with Boost OC 2 GB DDR5 to replace my previous RAM and graphics card. Will they be compatible with the ASUS M5A78L-M LX motherboard? Also can I use a Corsair SMPS CX500 500 Watts PSU to power these up?

Yes, they're compatible. To get the DRAM to run at it's rated 1600MHz, you'll need to enable the DRAM Overclocking Profile (DOCP) in your BIOS, but that's easy.

For the PSU, your system with that GPU should have a minimum of 500W with at least 24A on the +12V rail - the CX500 meets the minimum voltage requirement and provides 38A on the +12V rail. If you already own it, it will work but you shouldn't plan on doing any overclocks. If you have not purchased the PSU yet and would like some headroom to overclock your CPU and/or GPU, you should look at getting a Tier 2 or higher at 550-650W.

Thank you for the prompt reply. I don't have a PSU at the moment. Would a Corsair VS550 550 Watt PSU do the job? I am on a tight budget at the moment so it would be appreciated if you could suggest some other PSUs if the aforementioned PSU isn't proper for my needs. I did look at the list but most of them are unavailable in my country.

My needs mostly consist of running multiple 3D sculpting softwares and/or image editing softwares at the same time. In general I tend to use a lot of softwares at the same time.

I have never really tried to over-clock since I don't know how to.

Also would a SSD make any difference in using multiple softwares at the same time? I was told it only boosts start up time of the OS and softwares.

Between the two, I'd stick with the CX even though it's rated at a lower wattage -actual max outputs will be closer than the specs imply. The CX has better components and is more efficient. If you're not planning to do any overclocking, you should be just fine with the CX500.

An SSD will will boost your OS boot time and your file retrieval/transfer rate considerably. If you run lots of applications simultaneously however, especially with editing, it may be better go with a good 7200 RPM HDD and bump your DRAM to 16GB instead of 8GB. It'll take longer than an SSD to start your system up and retrieve and save large files, but your applications and processes will be much snappier.
