Hi guys
Im Thinking About buying a HIS ATI Radeon HD4890 1024mb 850core 3.60mem 256bit GDDR5 DVI HDTV HDCP PCI-E
just some questions about it
What type of cpu would be good with this so it wouldn't bottleneck the cpu ? quad core or dual? if so what ones?
and will this work fine in a Nvidia based motherboard or should i get a Amd based board ?
and what speed ram should i have with this card 1066 or ddr2 800 or even ddr3?
Hello and welcome to the forums mate Both Dual Cores and Quad Cores will be fine for that card,it depends on the model that u are considering.
It will work in a Nvidia chipset(In single mode) but if u need CrossFire them u have to go for an motherboard which supports CrossFire.
About RAM,that isnt really much related to VGA,RAM speed mostly depends on if u want to OC or not.
also would their be much difference between ddr2 667 ram and ddr2 800 ram ?
as in if i had 4 gig of ddr2-667 would it be worth getting 8 gig of ddr2 -800 ram ?
i have a Athlon X2 6000+ Dual Core 3.0 2x1024kb L2 Boxed Socket AM2-125w
so my cpu will not bottle neck this card? i need to be 100% sure
Wait! It will hugely bottleneck your HD4890!!!
I have the same CPU and HD4870 and the result was horrible!(even clocked to 3.3 Ghz) When I upgrade to PII 940 the performance went up by 40-50% ( on GTA IV boost was 120%)
Ath X2 6000+ is HUGE bottleneck for HD4890 !

or the
Phenom II TripleCore 720 2.8 6mb cache Boxed Socket AM3 - Black Edition
or just screw it and go the
Phenom II QuadCore 810 2.6 4mb cache Boxed Socket AM3
not sure which would be better
also how would these run with my ddr2-667 ram with the HD4890
Interesting when people mention bottlenecks, you will not be able to get the full benefit of the card sure but system isn't going to crawl to halt.
Is there not performance reductions for putting AM3 into a AM2+ board? If you are forking out for the 4890 then I would go the full way or, at least, choose a lower spec card and upgrade the processor and mobo if money was an issue.
Depends on the type of ram (manufacturer and model) and if you are going to overclock the CPU and possibly the hyperconnect. If you leave it stock then it shouldn't matter that much. Some PC6400 speed ram can be OC'ed to 1066 but you lose timings
id say with my ddr2 667 ram leave it as stock
then get 8gig ddr2 1066 later and oc it to 3 gig?
so this cpu (TripleCore 720 2.8) their would be no bottle neck with the g card ? i just wana be 100% sure
yep, just go for Phenom II 720! It will be perfect for the HD4890. In almost all games PII 720 performs as PII 920, but it is cheaper, so just go for 720 it wont bottleneck you.
P.S. do NOT go for older phenoms, they are way slower than the new PII's

AM3 is the same as AM2+ exept much more expensive DDR3 memory wich will drive your system 1-2% faster than DDR2 memory! google it! I'm not sure if TH has some benches, but if thet do - DO NOT trust them as we all know that they are faking them (just google it)

if your running win xp 32bit no point for the 8 gig since xp only reads up to 4 gig
im running AMD setup because well ATI is now owned AMD my setup is AMD Phenom II x4 3.0 Ghz black edition 940 denab with a fat Thermaltake 140mm fan heatsink, with ASUS M4A79 Deluxe motherboard, ocz reaper 4 gig 1066mhz ddr2 ram, Sapphire ATI Radeon HD4890 Overclock edition, powered by Thermaltake 1000watt power supply and my stuff runs smoooth like butter temperatures are cpu 30-36 degrees, motherboard 30-32 degrees, and the gpu runs on the warm side but i understand this is normal at 60-70 degrees i recomend buildin that especially since AMD is so much lower in price compared to intel build oh yeah RUN WINDOWS XP PRO VISTA SUCKS wait till win 7 is released before upgrade from XP just skip vista

*update* sorry didnt read the whole thread xD (ignore post)
The large increase in fps in GTA IV is from the extra cores in the PII. (cpu intensive) i agree though it will bottleneck it a bit but i think its still worth the upgrade or you could get a 4870 which would make more sense. http://www.newegg.com/Product/Prod [...] 6814121288 (A lot cheaper)
