So I haven't done any PC gaming and was wondering what sort of gaming experience this setup would bring.
2x 4GB Vengance
2x GTX460 Asus 768MB
2x 320GB Samsung F1 RAID0
The last lot of gaming I did was PS3, things like GTAIV, SFII and GT5 but ended up with no time and sold everything.
My questions are -
Bottlenecking, what is it, any issues?
Using 768M instead of 1GB cards, any issues?
Would extra RAM, more than 4GB improve gaming?
Would an SSD dramatically improve gaming?
What level of system is needed to produce a similar gaming experiance as the PS3?
I've just been sent Mafia II with PHYSX free with a card I brought and want to try it out, any views on PHYSX and other decent game recommendations would be cool.
Thanks to anyone that can be bothered to answer all these questions, even if you know about some still answer.
Can't see any bottleneck. The 1Gb cards are much better for the money especially at high res. Extra RAM over 4gb will not make much difference but may be more future proof. SSD will make things load quicker I am not sure if there will be other benefits. Don't really know about the PS3 question my best guess would be around an Athlon x3 with a Radeon 5770 but some games that are written for consoles are coded badly for PC need more.
The system you listed should be able to run any game out there at pretty high settings. You may not be able to play at very high frames at the highest settings due to the smaller texture memory size, but I dont see anything running at under 40 fps on your rig.
When one device has to wait a "significant" amount of time on another device. "Significant" in this case means milliseconds.
The main bottleneck in a system is the hard drive. Everything waits on the hard drive. But you clearly mean the CPU and GPU. If the CPU cannot keep the GPU fed, the CPU is the bottleneck. Likewise, if the CPU has to wait for for the GPU to finish rendering the last frame, the GPU is the bottleneck.
It's difficult to build a "balanced" system because games have different requirements.
I grabbed an OCZ Vertex 2E 60GB for £80 on offer and am very impressed with it. I don't like a load of programs installed (I'm a bit of a minimalist) so 60GB was fine for me but they do 120GB versions as well. That being said, I think there's a new SandForce controller on the horizon so that may be worth waiting for.
I often watch HD Video on my HD TV from my PC. I just use an HDMI cable straight from the PC to the TV. Your 460's should definitely have HDMI.
A SSD will not speed up games, just application loading and boot up speed. Will be a good boost for video editing and encoding. Game speed, once loaded, is mostly RAM/video card/CPU. If you don't have enough RAM to load the game fully in it, it will use the drive a bit, but if you benchmark things, I don't think you will see a noticable improvement. You generally need about a 20-30% improvement in speed for someone to say "hey, that is faster". 1080p will be fine on your system.
Right, what about CAS7/8/9 ram timings, is it worth the lower timings, ie a noticable differance?
Also just out of interest if this machine was the same setup with these changes, which would perform better gaming.
2x3 gig RAM
Lets say both cpu's are clocked at 4ghz, the ram is the same timings but obviously dual and triple.
Timings, by themselves, you would not notice. However, lets say you got an SSD, got tripple channel, tweaked the drives, got rid of some backgrond programs, etc.. then it will all add up to a noticable difference. A few 2-3-4% speed upgrades will add up eventually.
