my hp pavillion pc configuration is
PentiumD 820 (S) DC 2.8 GHz
800 MHz front side bus
motherboard name: Asterope2-GL8E
2 GB DDR2 ram 667Mhz
Hard drive 160 GB SATA 7200 rpm
GeForce 7300LE 64 MB DDR memory
300W HIPRO smps +12V = 19 A
I am planning to run most of the fps and the rpg at 1280*1024 with 2xx or 4x AA on a 19" hp monitor like
last remnant, gears of war 2 stalker clear sky cod5,6 , fallout, crysis warhead, oblivion etc
will there be any bottlenecking problems with my cpu
should i go for palit , sapphire or powercolor etc?
the 4670 is too slow to take advantage of 1GB, the extra memory is more of a gimmick then a performance booster. If the 1GB card is the same price as the 512mb card then there's no reason not to get it, if the 1GB card costs more then save your money.
Palit cards are fine. Some people prefer the over-clocked HIS card
what about 1 gb 9500gt?
some people say that both the cards will give same performance without any major difference. so should i so with nvidia or ati?
if i lower my playing resolution to something like 1024x768 with 4xAA and all then do i need to change the smps
with that rig I think you will get best results on most of the more modern difficult game engines if you lower your resolution. You might still have to tweak the the game settings on some games. I would turn the AA off completely in Crysis and other really graphically challenging games. It doesn't matter how great a game looks if you can't get smooth frame rates. Just keep lowering everything until you can run smoothly.
There's almost no situation where having a 9500gt with 1gb of memory makes any sense. In fact it should be avoided because the 1gb version always uses DDR2 memory and the DDR3 version of the card is better. At your intended resolution any card with over 512mbs is pointless actually.
But none of that matters as the HD4670 is a much better card. If you really prefer nvidia what you should be looking at in that price range is the 384/768mb version of the 9600 GSO but I doubt your PSU could handle it anyway.
