I had a PC with radeon 4870X2 for about half a year on and off and found it very prone to graphics glitches due to overheating or other things, and also slower on some games than it should be due to, I guess, the poor handling or more than one graphics core. I remember people recommending I turn one off - Bit of a waste.
Are other SLI options worth it? Is there really a difference? Bearing in mind I tend to run at 1920x1440 and will be upgrading to 1920x1600 when organic LEDs get themselves sorted out (I hate backlights on LCDs the washed out greyish black on games like Doom 3, FEAR etc, using high-end CRT instead) and prefer to run stuff on max settings. I remember Crysis ran on max settings but was quite buggy with LOD for some reason with rocks only showing when up close while rest of things worked fine, stuff like that. I also use my PC for business but I am planning around games first because they need the most juice and anything that works for high-end should be fine for everything else I think!
I'm going to make a fresh start and possibly build my own PC this time around, last one was from Overclockers UK, who I foolishly gave a chance even after reading various negative web reviews (mixed with a few "oh they're fine" ones which I guess may have been astroturfing).
Going for watercooling for sure as I want a quieter PC this time, 4870X2 revved up like an aeroplane at times even with about 6 fans on Antec 1200 case going at full blast:
Also, thinking about the possibility of having USB extensions and monitor lead extensions to have the actual box in a different room from monitor and accesories - how viable is this, one thing I remember hearing last time I investigated it was that USB power tends to drop off after about 2 metres or something? And I'm worried that routing through a hub would possibly slow things down. I know VGA cables have a limited range, but I thought I could work around that by having the DVI to VGA adapter near the monitor and having the actual cable DVI still.
Thanks for any help, hopefully I won't have to post in multiple forums to get some reliable info like last time around I researched
p.s. Prev PC specs was Corsair 1000HX PSU, graphics card as prev mentioned, Q660 oc'd@3ghz (didn't last long though) 8gb corsair ddr2 can't remember speed, with vista (only chosen because of the larger ram allowance) - obv win7 + i7 this time, unless there's any new cpu coming out soon? i7 was available when I bought this PC but I skipped due to rumours of poor gaming support
(Oh and will be going with nvidia card(s) this time - much as I am not interested in brand names and despise pandering to a monopoly - I got pretty sick of games developers choosing to support Nvidia to more of an extent than ATI with all the "way it's meant to be played" anti-competitive BS which, I think if gaming was more mainstream the government would care enough to squeeze the same way Microsoft have been.)
Also looking at Scan 3XS systems, with the possibility of maybe picking the parts and having it made rather than picking a named/brand one as I'm not really bothered about that and they seem to have quite a mark-up. From what I have seen almost £100 might be well worth avoiding the hassle of learning how to overclock, watercool properly etc and leave it to the guys who do it every day (who seem pretty friendly unlike OCUK who just seem to want to keep you as far away as possible once they've got your money off you). I was impressed by "# The engineers care about the systems they build. # They use a rigorous build process to ensure the systems built are tested to a set standard. (We’ll share these results with you) # Systems are fully stress tested and QC checked prior to despatch" and the actual guys taking pictures of the machines and posting on forum etc, well they actually do seem to care about their job like the marketing pages claim rather than just chucking them out without testing. However on another thread I replied when I said about overclockers someone said something bad about scan and it got deleted (here you can see where my post was edited where I was quoting another person and replying to their vanished message saying scan had wronged them somehow (I can't remember who it was now so I guess the memory-holeing is effective of sorts), and the message after mine sounds weird because the other messages are missing), so I'd like to hear anything really, I'm a lot more wary now (hence my questions about the use of premium rate numbers for customer services in my other recent topic)
another edit: added links to previous threads from couple years when I was last researching/planning.
