Hello everyone, I am familiar with computer building although it has been some time, we are talking 2007 since my last build, so I am a bit rusty. Since then I know there have been a lot of advancements and know things are not as straight forward as they used to be. When it comes to things like GDDR3 and GDDR5, I am getting all sorts of mixed results when searching online with no actual answer. I know that they are dedicated memory for the graphics card so it does not matter if a GDDR5 graphics card is installed in a DDR3 motherboard. However, there is no definitive answer on these when it comes to dual graphics, as in combining the APU and GPU for better performance. I say it like that just to clarify because I see some people consider dual graphics as using two monitors and consider crossfire as combining graphics cards. I am finding it all depends on who you talk to I guess. Okay back on subject.... lol
I am planning on building this system:
- AMD A10 7870K APU with heat sink and fan (I cannot currently justify buying a A10 7890K)
- Gigabyte GA-F2A68HM-H motherboard
- ADATA XPG V1 (AX3U2133W8G10-DR) DDR3 2133 MHz 2x 8GB memory
- XFX R7-360P-F22M 2GB 1050MHz GDDR5 graphics card
- Radeon R3SL240G SSD (for gaming)
- HGST Travelstar 7K1000 2.5-Inch 1TB 7200 RPM SATA III 32MB Cache
Main uses of this PC will be for Flight Simulator X: Steam Edition with add-ons like Traffic 360, Active Sky Next, and various freeware AFCAD / Scenery files. The goal is to run this sim smoothly without jitter at minimum 30 FPS with maxed scenery and global setting, along with 60% Airport, 60% General Aviation, Medium Ground Vehicle, 15% Traffic, 15% of leisure and carriers ships settings at 1080P.
Secondary uses will be for media entertainment such as Amazon Prime Video, Amazon Music, some light Online Gaming and playing Company of Heroes: Steam Edition (max settings).
Third uses will be for everything else such as internet surfing, email, etc.
I am wanting to know if I can successfully "crossfire" the AMD A10 7870K DDR3 with the XFX GDDR5 graphics card to better performance. Otherwise I will have to, what looks like for my budget, downgrade to an overclocked MSI R7 250 DDR3.
Also need to try and figure out if for my particular setup, if 4x 4GB would be better instead of 2x 8GB for the 2133Mhz RAM.
Any knowledgeable expert suggestions would be quite helpful in this matter!
Thank you ahead of time for your help!
